Inquiry About AI Summary Feature for Tags in Dovetail

Hi Dovetail team, A while back, in each tag, there used to be an AI summary that recapped the tag's highlights. It used to be on top (screenshot); however, now I can only see an empty description! Is this feature no longer available? PS: The current description area is also confusing. The info button has the AI sparkle, which I thought I could use AI to generate a description, but it's not the case!
