Hi @philnickel
No problem!
To show your value from a specific category in a template you use the second parameter of get_field or the_field which is normally used for post IDs.
For categories you use
the_field('fieldname', 'taxonomyslug_categoryid')
For users you’d use
the_field('fieldname', 'user_'.$user->ID)
Etc etc
so in your case it would be
the_field('category_beschreibung', 'category_29')
