I saw a recent post about this issue, but the post is blocked. Therefore, I start a new one.
We use a glossary in a moodle course and set the entries with auto-link.
In the settings of the glossary, I set "yes" to autolink:

The settings for the entries are as follows:

Furthermore, I enabled the filter "auto-link to glossary":

And when I click in the course on a word, which is auto-linked, I get multiple pop-ups:

We use the version 4.0.8 (Build: 20230424), Boost theme, Tiles format and every entry is concerned. We use glossary on the site, but not the same twice.
Thank you for your recommondations and help.
Regards,
Lydia
