Sims still autonomously building unwanted romantic relationships

Since the new pack, and having to create a new save for it, I've noticed that my sims are autonomously building romantic relationships (again) even though I've turned those configurations off. It's happening with NPCs, townies that I rotationally play with, and with new households I create. It's kind of annoying to play an unplayed household and find out they fell in love with a Landgraab (or whoever) before I've even played them. And it's mostly with Sims who are already married. I don't want aaaaall of my Sims to be unfaithful. 😬😅 If I wanted to play that way, I wouldn't have turned off those configurations.
