Calling `acl` command in section titles count as "first appearance"

[tplobo]

Using the following code:

\ac{SS}

\section{An analysis on the \acl{SS} \& multiple studies}
\sectionmark{An analysis}
\label{sc:analysis}

\ac{SS}

prints in my PDF:

Safety System (SS)

2.1) An analysis on the Safety System & multiple studies

SS

which I believe is incorrect. The use of acl should not be flagged as "first appearance". This is apparently not the case when the command in called in \chapter titles instead of \section titles.

I tried applying acl*, but it is apparently the incorrect procedure. I will be using \acl{SS}\acreset{SS} but I believe this is a bug that should be fixed.

I don't follow the complaint: You use the acronym with \ac{SS} which as the first call prints the first appearance, you then call \acl{SS} which prints the long form, and then \ac{SS} which prints the short form. This is all as I would expect, what do you expect?

Oh, you're right @dbranford, I forgot to add the \acresetall command that I used for debugging to my example! Sorry for that =P

Here's the correct example that is leading to my issue:

\ac{SS}
\acresetall

\section{An analysis on the \acl{SS} \& multiple studies}
\sectionmark{An analysis}
\label{sc:analysis}

\ac{SS}

which produces:

Safety System (SS)

2.1) An analysis on the Safety System & multiple studies

SS

Furthermore, I am still trying to understand why, but my original solution (of adding \acreset{SS} after \acl{SS} in the heading) only works within \section, but not within \chapter. Here's the example:

\ac{SS}
\acresetall

\section{An analysis on the \acl{SS}\acreset{SS} \& multiple studies}
\sectionmark{An analysis}
\label{sc:analysis}

\ac{SS}

and associated error message:

Package hyperref: Token not allowed in a PDF string (Unicode):
(hyperref)	removing `\acreset'.LaTeX

If instead I place the \acreset{SS} command right after (and outside of) the \chapter{...} command, it also does not work. I am forced to use \acresetall to ensure the "SS" acronym gets reset. Here's the example of what works:

\ac{SS}
\acresetall

\section{An analysis on the \acl{SS} \& multiple studies}
\sectionmark{An analysis}
\label{sc:analysis}

\acresetall
\ac{SS}

Ah, then I follow. This is expected behaviour, if you don't want the usage of \acl to count, use \acl* as the question you linked to says, if you need that single usage to count as a usage for the list of acronyms make an appropriate compensatory \acuse just before printing the list, or if you want all defined acronyms to appear in the list use the list/display=all key.

I can't reproduce the last part of your comment though, calling \acreset after a \section with an \acl in it gives the expected first appearance for the final \ac

\documentclass{article}
