CAS Glitch: Unnaccessible Colour Swatches

Hi all,

I have for some time now been experiencing this issue on CAS, where I can hover my cursor over a certain colour swatch in CAS, but it won't highlight or select it. It is doing it for clothes, accessories, make-up, etc, and I don't think I have seen it reported before.

It looks like it is because the cursor goes a bit off and therefore I would have to click slightly aside to select the colour I want, but that is a problem I only encounter in the Sims (so it's not my mouse itself), and only experience a tiny bit during gameplay but constantly on CAS. And because the colour swatches are close together on CAS, I don't have the room to click next to the colour I actually want, if that makes sense.

To be more specific, in the screenshot attached, the Sim is wearing the blue version of the tank top selected (it's highlighted). I can select the colour swatches from the first line, or the two left ones of the second line. But that's pretty much it. Past this kaki swatch that pops up, my cursor can go as far right as I want but it refuses to bring up the other colour swatches, and I just can't select them!

I have tried taking out all my mods and CC, and repairing the game, but I'm still having the same issue. Has anyone else had it and knows how to fix it?

Thanks a lot
