Tags are not visible in Tags Section

I have documents which have automatically assigned tags based on their group membership but those tags are not shown under the tag section in Global. If I search for “tag:tagname” I see the resulting documents. Any hints.

Welcome @thomas.krampe

Group tags aren’t listed in the Tags group for a database.

You could tag the parent group and enable File > Database Properties > Inherit Tags of Groups.
