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

Product: The Sims 4
Platform: Mac
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.68.154.1220
What expansions, game packs, and stuff packs do you have installed? All except Batuu
Steps: How can we find the bug ourselves? Look at a sim's profile (click on the portrait in relationships)
What happens when the bug occurs? If the sim in question has been raised from toddlerhood, their toddler trait appears in the profile.
What do you expect to see? I expect to not see their toddler trait, as this is hidden and irrelevant after they age up to being a child.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Yes - update to 1.68.154.1220

I've just started having this issue after the most recent update (to 1.68.154.1220, released 10th Nov 2020). The toddler trait now appears in the new Sim Profile, as well as when you hover over the sim in question in the relationships panel.

The toddler trait also originally appeared in the Simology panel, but after a game crash that seems to have been resolved. 

The error doesn't seem to be happening with all sims raised from toddlers, but can't investigate that further as the game crashed again and now won't run long enough for me to check!
