[OPEN] Toddler traits in Relationship panel after aging (Patch 1.59.73)

I'm having the same issue in my game. I did notice it before, all 7 toddlers I played for a 7 toddler challenge got stuck with their toddler trait in the relationship panel of other sims (they don't actually have the trait anymore).

In the same save I have moved on and started a family and three of the kids have aged up, the first one inititally had his toddler trait (inquisitive - now outgoing) stuck, but it seems to have solved itself now. The second kid, (independent - now geek) still has this issue. The third child however (angelic - now cheerful) doesn't. Not sure if she did, she only aged up two in game days ago and I haven't actually checked.

So it's definitely weird, but maybe there is some way to fix it?

Come to think of it - I did apply face details through fulleditmode on kids 1 and 3, but not on kid 2. Could be completely unrelated - I did edit their teeth for all of them. But that is one thing that's different between them. I'll see if doing something in CAS may fix it. I don't think so, but you never know.
