friend list

sims 4 on pc NO MODS INSTALLED. since two-three updates ago, every time i travel or use the socialize with friends on pc i have a person my friend travel list but no on my friends list. it took me two weeks and a half to realize, whenever i use the pc in my game, it adds a random person on my social/travel friend list. i know it a bug, because others complained about it years ago, and now it's back. everything else is fine.
