cleveref does not work together in sv classes with envcountsame option

Question

I posted once before about this issue, here, but would like to start a new thread with more information and a MWE. I hope that's OK. (In the old post I did not very adequately explain the situation, and forgot an MWE, for which I apologize. But it means there were some comments based on inaccurate info, which makes it a less useful thread.)

The issue is that in sv classes like svmono, adding the envcountsame option causes cleveref to not correctly identify the namerefs of environments. Everything appears as "Theorem", regardless of environment.

One workaround, which I found here, is to define a custom \label command. That works mostly, but not completely. Some environments, for whatever reason, continue not to show correctly.

Examples of environments that work: proposition, lemma, corollary, remark

Examples of environments that don't work: exercise, question

I cannot find anything in the svmono class itself that would account for this. As far as I can tell, they are all defined identically.

Specifying \Crefname for these environments does not seem to help. In fact, it does not seem to be a cleveref issue, at least not entirely. For example, for the environments that don't work, \namecref and \labelcref still work, and pick up the information correctly.

Would anyone have any insights on what might be going on, and even better, any ideas on how to fix this behavior?

I attached the MWE below.

\documentclass[envcountsame]{svmono}

\usepackage[capitalise]{cleveref}
\usepackage{thmtools}

\makeatletter
\newcommand{\labelx}[1]{
    \relax
    \ifmmode
        \label{#1} 
    \else 
        \ifnum\pdfstrcmp{\@currenvir}{document}=0
            \label{#1}
        \else
            \label[\@currenvir]{#1}
        \fi
    \fi
}
\makeatother

\begin{document}

\crefname{exercise}{Exercise}{Exercise}
\Crefname{exercise}{Exercise}{Exercise}
\crefname{question}{Question}{Question}
\Crefname{question}{Question}{Question}

\begin{proposition}\label{prop_with_label}
    Proposition with label. 
\end{proposition}

\begin{proposition}\labelx{prop_with_labelx}
    Proposition with labelX.    
\end{proposition}

\begin{corollary}\label{cor_with_label}
    Corollary with label.   
\end{corollary}

\begin{corollary}\labelx{cor_with_labelx}
    Corollary with labelX.  
\end{corollary}

\begin{exercise}\label{exer_with_label}
    Exercise with label.    
\end{exercise}

\begin{exercise}\labelx{exer_with_labelx}
    Exercise with labelX.   
\end{exercise}

\begin{question}\label{quest_with_label}
    Test    
\end{question}

\begin{question}\labelx{quest_with_labelx}
    Test    
\end{question}


Let's cite these, now.

With label, nothing works right: \Cref{prop_with_label}, \Cref{cor_with_label}, \Cref{exer_with_label}, \Cref{quest_with_label}.

With labelX, some things work: \Cref{prop_with_labelx}, \Cref{cor_with_labelx}. 

But some things still don't: \Cref{exer_with_labelx}, \Cref{quest_with_labelx}.

\end{document}

Svmono is dead and a mess. A dead mess. Or a messy corpse; you name it. I also don't know how to reference questions.

After this short but delightful complaint (due to my fighting with issues expressed in, say, svmono+enumitem: how to discourage a page break between a remark head and a following list and With svmono, how to introduce more horizontal space between a theorem head and the theorem contents without occasionally introducing vertical space?), let me tell you that I still know how to reference exercises, and here is what I do:

\documentclass[envcountsame]{svmono}% using v5.10
\pagestyle{empty}
\usepackage{graphicx}
\usepackage[capitalise]{cleveref}
\crefname{exercise}{Exercise}{Exercise}
\Crefname{exercise}{Exercise}{Exercise}
\Crefformat{exercise}{Exercise #2#1#3}
\crefformat{exercise}{Exercise #2#1#3}
\begin{document}
\begin{exercise}\label[exercise]{exer_with_option}
    Exercise body.
\end{exercise}
\begin{question}{Question head.}
    Question body.
\end{question}
\Cref{exer_with_option}, \cref{exer_with_option}.
\end{document}

Pdflatexing this yields

You can try \label[environmentName]{labelName} with lots of environments (for example, with remarks and definitions).

As for questions, I wouldn't know how to reference them anyway because they are not numbered (in my test) for svmono v5.10.
