Article comments on UCP wikis, as well as message wall posts and Discussions post, are not shown in the Contributions page, but in the Activity page. It is indeed a problem that anon users currently don't have this page (they don't have a user page or a message wall either).

I think it is already known to Fandom staff, but you should probably still bring it up officially through Special:Contact.
