20214 Jealousy Issues

All my sims are getting jealous for no reason with their partners and none of them have the jealousy trait. I saw there were issues in the past but didn't find answers. None are romantic but I do have the faithful trait. for my main couple, both sims have the faithful trait but only one gets jealous. my other couple doesn't have the faithful trait at all and this recently started. I've been playing on PC for over 2 months, and this started happening today. I am playing with mods.
