Game marks as acquaintances even though we are best friends/romance interest

The game marks as acquaintances even though we were best friends and had a romantic interest. my sim had an awkward conversation and the romance/friendship bar decreased just by a little bit. since after this, the game has mark this specific sim an acquaintance even tho we were best friends before. all of my other sims friends in the relationship panel all shows correctly as friends, best friends, acquaintances, good friends, etc. look at the friendship bar, its full, and the romantic bar is halfway, tho the game still calls it as acquaintance
