Andrew's accessories mod broke my game?

I downloaded andrew's accessories mod because I though more umbrellas would be fun. things were going great untill out of nowhere one of the umbrella mods duplicated themselves and replaced the og umbrellas? did know that was possible but that's what happened so I though "no problem i'll remove that umbrella pack." despite this they were still in the game? so this time I removed all umbrella related content and viewed the integrity of my game files (steam) and they're still there?! i've never seen something like this happing with cc before and I just want to get the og umbrellas back now. is there something I could do to fix this in sims 4 studio? I would just like both my umbrella mods and the og umbrellas to co-exist like they were before this all happened out of nowhere?
