3.2.1 (AZCE) Heir Is Not Inerheriting Properly

Game Version
3.2.1 (AZCE)

All of the above

No

Please explain your issue is in as much detail as possible.
In an ironman game where I was able to create Rome and reform the Hellenic Faith my eldest Daughter is only inheriting the Empire along with my counties, but not my Kingdom (Greece) or the Collegium Potificum.
I've made sure that all titles I can set crown laws in have Absolute Cognatic Primogeniture, in addition to the ability to designate an heir through the reformation.
Designation aside, she is my eldest Daughter, and with these succession laws I don't see any reason why she wouldn't be first in line for all of my titles. I can see that I can grant both of these titles to her, so there is a "workaround", however this does not seem to be functioning as intended.

Steps to reproduce the issue.
1. Reform Hellenism
2. Create a Feudal Empire
3. Usurp Byzantium (this seems to make Byzantium default to Feudal Government instead of Imperial)
4. Recreate Rome
5. Set all inheritance laws to Absolute Cognatic Primogeniture

Does Born in the Purple still matter for the Roman empire under primogeniture? Try giving her the Despot title

I gave her the Despot title, but nothing has changed in regards to the Collegium, it's still being inherited by my second born. None of my children have Born in the Purple, only my character.

What are the succession laws for Greece and the Collegium Potificum?

Keep in mind that Born-in-the-Purple (and Despot) only apply to the empire, not to any kingdoms you happen to hold.

Rome and Greece have been manually set to Absolute Cognatic Primogeniture, and the Collegium follows the succession of the primary title so it is the same.
In the screenshots I included you can confirm this, and weirdly my daughter appears as second in line for Greece. On top of that I can designate any of my children as Heir, except for my firstborn son (who is the one set to inherit Greece and the Collegium).
