Cannot enable custom user data in realm user control panel

Following the docs to enable custom user meta data on a realm cluster does not currently work, there are no options availble in the database name dropdown. Are there more steps required to make this work?

It looks like you don’t have a database in your cluster yet. You can create one by going to Rules -> Add Collection.

Hrmm, I can’t see any “Add Collection” button in Rules. I do see my database and collections in there however. I tried turning devmode on to see if that would open up the option or show my database name in the dropdown but still no luck.
