Database prefix is not working correctly

Summary

After Upgrade from 3.2.11p2 to 3.2.12p1 new created databases will be created with prefix CLIENTID but if I edit databases CLIENTID not shown as non-editable prefix.

Steps to reproduce

1. Login as Client
2. Create a Database
3. Edit the newly created database.
4. Now the DB Name is created, but the prefix is not in the prefix field. Also, the Database name isn't editable.
5. Login back as admin
6. Edit the newly created Database, and you will see the same.

Correct behaviour

Prefix field should be correctly filled out.

Environment
