FFS - Variables disappeared in Manage Logics

Hello,

I've encountered a bug(?) where now none of the defined parameters are existing in the manager logics.

I was exploring the "Manager User Attributes" and had created a user attribute for a product, and then deleted it.

Now when I create a new User Logic/ my existing logics, there are no defined parameters, making my logics useless and no longer working.

How can I bring back the parameters? I've just added them back manually but this seems extremely strange...

Please note i'm on 22x
