Aliens don't have new link feature in CAS (like Vampires and Mermaids)

Product: The Sims 4
Platform: Mac
Which language are you playing the game in? English
How often does the bug occur? Always (100% of the time)
What is your current game version number? 1.52.100.1220
What expansions, game packs, and stuff packs do you have installed? Every single one.
Steps: How can we find the bug ourselves? Enter CAS mode and create a new Alien Sim, get an Alien Sim from the Gallery, or edit a household with an Alien Sim.
What happens when the bug occurs? Aliens will not have the feature to link their two forms. The feature was added in the latest update, Vampires and Mermaids have the feature working as expected.
What do you expect to see? For Aliens to have the same link feature as the other occults.
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes, but I took them out and cleared the cache to test this out without mods, the problem still occurs.
Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. June 18th, 2019 Patch Update

So when I try to make an Alien all I get is the disguise with no option to "link" it to the main form like we get with Vampires and Mermaids. Also when I hit randomize if I am on the Alien form only the Alien form will be randomized and the disguise will not change at all, but if I am in the disguised form both forms will be randomized successfully. I don't remember if this was always this way? But I don't think so because the Disguise will get the little loading icon as if it was getting randomized but then show up exactly the same afterward. If this is a separate issue please let me know and I'll make another post for that, this is my first time posting here.

I have looked everywhere and I can not find anything saying that this is intentional, but neither can I find anyone else with the same issue. If this is intentional I would like to take the opportunity to ask that please the link feature be added to Aliens as well, I could understand why maybe it would be intentional since Aliens have a "disguise" not an "alternate form", but every sim player is different and personally my gameplay style is for both forms to be as similar as possible and it's been annoying so far, I was very excited when this new feature was announced as I thought it would apply to all occult types.

If it matters I am also affected by the skin details not showing up on other outfits bug, which is already a known issue for MAC users. Doubt they are related but since its also a CAS issue I thought I'd mention it.

Thanks for any help!
