A couple of questions about eDocman attachment search

Dear support,
I tried my Joomla 4 search to check if attachments where shown.

First of all, the shortcode in the Search result page is displayed and not processed (see attachment). How to fix the document view?

Then I saw no attachment . Investigating into the plugins, I opened the active "EDocman - Indexer plugin" and found this: 
File Extensions with an empty input. What should I write here? Comma separated or what? An helping tooltip will be fundamental...

Regards
Lorenzo

Hi Lorenzo,
