Random sims spawning on my lot

Every time I try play lots of random sims keep spawning on my home lot. Whenever I try to get rid of them new ones just spawn in. It’s causing issues with the game as everytime I try to invite sims I actually want over they don’t come as I assume there are already too many sims at the lot. I’ve tried to repair the game, I’ve deleted the localcashe file from its folder and have also uninstalled and reinstalled it but it’s still happening. The lot is a residential lot with no lot traits that would mean there would be more sims there. Anyone having the same issue?
