No option to change sim's eye colour after ROM

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? 1.58.69.1010
What expansions, game packs, and stuff packs do you have installed? All
Steps: How can we find the bug ourselves? Have a custom default eye colour replacement in your mods folder, then try to change a sim's eye colour in CAS
What happens when the bug occurs? Every time I try to change a sim's eye colour, whether they're pre-existing, new or made with the story mode, the option to change their eye colour is gone and every single sim is stuck with the same brown coloured eyes. Removing the default eye colour replacement from my mods folder solves the issue, but clearly something is broken for this type of CC to no longer work.

This issue has been ongoing for a little while now and it's really disappointing. Obviously it doesn't break the game and removing the CC eye colours does fix the issue, but I very much prefer to use CC eye colour replacements in my game and not being able to do this really affects my gameplay.
