There are several ongoing bugs related to the gallery, including bugs affecting favourites, followers/following and download counts. Most of them go all the way back to the gallery maintenance that was done last June.

Given that it's been so long since the maintenance disaster, I don't know whether EA even considers gallery bugs and issues priorities anymore; they seem to have been abandoned. For example, they originally said the newsfeed would come back, but it hasn't.
However, I hear there's a problem with the gallery that affects Lovestruck (gallery sims not appearing in the dating app), and I assume that Lovestruck bugs are top priority right now because it's a new pack that they want to sell, so maybe this means that the older gallery bugs will finally get some attention again. Who really knows, though?
