I renamed a project from Test to Test2 and it's key from TEST to TEST2, all went well, re-indexing was done. There is now a project Test2 with key TEST2, and the old one Test with key TEST is gone.
Now I would like to add a new project, again with key TEST, however I get the message:
Project 'Test2' uses this project key.
What am I missing here, Test2 should have key TEST2 and the key TEST should no longer exist?
