rejected submissions/favorites Options

[*paperplane*]

Excuse me if this has been addressed already, but I found that a large amount of the layouts I have added as favorites have been rejected or simply seem to no longer exist. The part where it find it questionable that layouts I liked enough to bookmark aside, it's a bit annoying that half the layouts in my list aren't there. How am I supposed to remove those from favorites? In particular, it tells me I have one favorite graphic when in actuality I have none. I guess this doesn't really matter as I don't even use layouts for anything anymore, but still I'm curious how I'm supposed to remove rejected layouts from my favorites.
