[LS] Cupid’s Corner: Can’t save matches/Previously saved ones disappear

I didn't have the pack back when the update mentioned at the top of the thread, when I purchased it I could save many matches (I hadn't realised what the limit was, and don't think I hit it).  At some point, I think after the last update (maybe?) I couldn't add any new sims to my saves at all.  As stated above, it looks like it's added someone, but there's no one in the tab.
