Makeup sliders revert to default in Live Mode

Product: The Sims 4
Platform: PC
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? 1.113.288.1020 (the March 6th update)
What expansions, game packs, and stuff packs do you have installed?: all
Steps: How can we find the bug ourselves? putting makeup on a sim and adjusting the sliders (hue, saturation, opacity, etc). then, going in game with the sim from CAS.
What happens when the bug occurs? instead of displaying the edited makeup swatch shown in CAS, it seemingly reverts to the default setting of that swatch in Live Mode.
What do you expect to see? the makeup displaying the same as it does in CAS in Live Mode.
Have you installed any customization with the game, e.g. Custom Content or Mods? i removed my mods folder entirely and the issue still persists.
Did this issue appear after a specific patch or change you made to your system? not entirely sure. i noticed it around the 1.113.277.1030 (Feb 25th) patch, and it hasn't fixed since then.

I took this format from a forum post that's 5 years old - wild to me that it's still a persistent issue all these years on. As mentioned, this bug has persisted over multiple patches, and I have genuinely no idea how to fix it. I've tried everything I can - I've repaired my game, removed my mods (it still was an issue without mods), I've deleted the localthumbcache. None of it has worked, and I'm getting frustrated as time goes on. I remember having this same issue a couple of years ago, but it just randomly fixed one day, and I have no idea what I did back then to fix it. As said, I've tried every possibility I can think of, and it's just not fixing my Sims. Any advice would be appreciated - or, ideally, this gets fixed for the millionth time.
