Redonihunter is correct. The AI Generated and No AI tags, specifically, do not appear under More Information. Only tags that are manually added appear there, while AI Generated/No AI tags are keyed to a question that you have to answer when submitting a project and don't fall under that.
This is dumb and itch should fix it.
That is technically correct.
But please see for yourself, how many of those games do have easily visible ai tags in the more information box.
