listof Command Malfunctioning - float Package

Question

Consider the following code for the creation of two new floats in an article:

\documentclass{article}

\usepackage{graphicx,float}
% The First Float Type
\floatstyle{boxed} 
\newfloat{BoxImage}{htpb}{csv}[section] 
\floatname{BoxImage}{Boxed Image}
% The Second Float Type
\floatstyle{ruled}
\newfloat{FloatEqn}{htpb}{csv}[section]
\floatname{FloatEqn}{Float Equation}

\begin{document}
    \listof{BoxImage}{List of Boxed Images}
    \listof{FloatEqn}{List of Floating Equations} 
    \section{New Float Types}
    \begin{BoxImage}
        \includegraphics{example-image}
        \caption{This is an image with the new float.}
    \end{BoxImage}
    \begin{FloatEqn}
        \[ E = mc^2 \]
        \caption{Mass-Energy Equivalence.}
    \end{FloatEqn}
\end{document}

the problem is with the list of objects it appears like this:

The list of the second object is behaving in an odd way, and I don't know why. So, if you can help I would be grateful.

Thanks in advance.

Answer 1

If you specify the same toc file (csv here you can't hav independent lists, the ouput is a little odd and I didn't trace what it is doing but you can use two exensions, csv and csw say and get

\documentclass{article}
\usepackage{graphicx,float}
% The First Float Type
\floatstyle{boxed} 
\newfloat{BoxImage}{htpb}{csv}[section] 
\floatname{BoxImage}{Boxed Image}
% The Second Float Type
\floatstyle{ruled}
\newfloat{FloatEqn}{htpb}{csw}[section]
\floatname{FloatEqn}{Float Equation}

\begin{document}
    \listof{BoxImage}{List of Boxed Images}

    \listof{FloatEqn}{List of Floating Equations} 

    \section{New Float Types}
    \begin{BoxImage}
        \includegraphics{example-image}
        \caption{This is an image with the new float.}
    \end{BoxImage}
    \begin{FloatEqn}
        \[ E = mc^2 \]
        \caption{Mass-Energy Equivalence.}
    \end{FloatEqn}
\end{document}
