Skill Cheat Not Working To Lower Skill Level

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? The latest as of March 9, 2025. For some reason it's not displaying on my GameVersion.txt file. 
What expansions, game packs, and stuff packs do you have installed? All except Business & Hobbies, Life & Death, For Rent, Horse Ranch, Journey to Batuu, Strangerville, Jungle Adventure, Parenthood, Dine Out, and Outdoor Retreat.
Steps: How can we find the bug ourselves? Use any skill cheat (stats.set_skill_level ...) to set a lower skill level.
What happens when the bug occurs? The skill level does not change.
What do you expect to see? The skill level should change to the desired level.
Have you installed any customization with the game, e.g. Custom Content or Mods? Never
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure 

Issue started after the patch on 18 September 2024 and has not been addressed/fixed since then. I have not installed any CC/Mods to my game. I tested the skill cheats for several sims, including an Adult, Young Adult, Teen, and a Child to no avail.  For each, I found that I was able to increase their skill levels but I was not able to lower any.  This is especially impactful for players who use the skill cheat as a workaround for achieving certain milestones for their sims. 

Thank you for your time and attention!
