MWE

\documentclass[11pt]{report} % use larger type; default would be 10pt

\usepackage{hyperref}
\hypersetup{
    colorlinks,
    citecolor=blue,
    filecolor=blue,
    linkcolor=blue,
    urlcolor=red
}

\usepackage[nopostdot,acronym,toc,section=chapter,style=indexgroup,nomain]{glossaries}

\newglossary[tld]{type1}{pref1}{ntn}{Title One}
\newglossary[tld]{type2}{pref2}{ntn}{Title Two}
\newglossary[tld]{type3}{pref3}{ntn}{Title Three}
\makeglossaries


\newglossaryentry{pref1:testone}{
                type=type1,
                name={Testing One},
                description={We are Testing One}
}


\newglossaryentry{pref1:testone2}{
                type=type1,
                name={Testing One Too},
                description={We are Testing One as well}
}


\newglossaryentry{pref2:testtwo}{
                type=type2,
                name={Testing Two},
                description={Now we are adding to Two}
}

\newglossaryentry{pref2:testtwo2}{
                type=type2,
                name={Testing Two Too},
                description={Now we are adding to Two too}
}

\newglossaryentry{pref3:testthree}{
                type=type3,
                name={Testing Three},
                description={Finally Three}
}

\newglossaryentry{pref3:testthree2}{
                type=type3,
                name={Testing Three Too},
                description={Finally Three Too}
}


\begin{document}

\gls{pref3:testthree2} and \hfill\\
\gls{pref2:testtwo}

\printglossary[type=type3]
\printglossary[type=type1]
\printglossary[type=type2] 

\end{document}

I'm getting three glossaries in the correct order, but:

1. only {pref3:testthree2} is being referenced

2. {pref3:testthree2} is being referenced by ALL types

Command to generate PDF is: PDFlatex + PDFlatex + makeglossaries + makeglossaries + PDFlatex + PDFlatex.

Any help would be greatly appreciated!

Answer 1

The problem is that you've used the same file extension for each glossary. This means they're being overwritten by makeindex and the same file is being read for each \printglossary.

Here's your edited MWE:

\documentclass[11pt]{report}

\usepackage{hyperref}
\hypersetup{
    colorlinks,
    citecolor=blue,
    filecolor=blue,
    linkcolor=blue,
    urlcolor=red
}

\usepackage[nopostdot,acronym,toc,section=chapter,style=indexgroup,nomain]{glossaries}

\newglossary[tld]{type1}{pref1}{ntn1}{Title One}
\newglossary[tld]{type2}{pref2}{ntn2}{Title Two}
\newglossary[tld]{type3}{pref3}{ntn3}{Title Three}
\makeglossaries


\newglossaryentry{pref1:testone}{
                type=type1,
                name={Testing One},
                description={We are Testing One}
}


\newglossaryentry{pref1:testone2}{
                type=type1,
                name={Testing One Too},
                description={We are Testing One as well}
}


\newglossaryentry{pref2:testtwo}{
                type=type2,
                name={Testing Two},
                description={Now we are adding to Two}
}

\newglossaryentry{pref2:testtwo2}{
                type=type2,
                name={Testing Two Too},
                description={Now we are adding to Two too}
}

\newglossaryentry{pref3:testthree}{
                type=type3,
                name={Testing Three},
                description={Finally Three}
}

\newglossaryentry{pref3:testthree2}{
                type=type3,
                name={Testing Three Too},
                description={Finally Three Too}
}


\begin{document}

\gls{pref3:testthree2} and \hfill\\
\gls{pref2:testtwo}

\printglossary[type=type3]
\printglossary[type=type1]
\printglossary[type=type2] 

\end{document}

An alternative is to use the starred form of \newglossary which constructs the extensions from the glossary label. For example

\newglossary*{type1}{Title One}

is equivalent to

\newglossary[type1-glg]{type1}{type1-gls}{type1-glo}{Title One}

This can be useful if you have a lot of glossaries as then you don't have to keep track of all the extensions. Since the glossary label has to be unique, this will ensure that the glossary file extensions don't clash with each other.
