Custom domains not showing custom domains

All my pages lost their custom page association. The custom domains are shown in the card:
But not in the custom domain tab, making it impossible to remove the domain and delete the project.

Do you have any CNAME records of the custom domain in your DNS for the zone?

Yes because I originally added them via the custom domain tab. But now they are gone. I already tried deleting the CNAME entry they still show up.
