renaming a database after it was converted from DT PE

The ReadMe for DT Pro says:

“When you are upgrading from DEVONthink Personal to DEVONthink Profes- sional, the application will copy your existing DEVONthink Personal database to your documents folder {~/Documents/DEVONthink.dtBase) and modify all paths, URLs and internal aliases accordingly if necessary.”

That’s wonderful, but I renamed the database (after quitting DT Pro, of course), and when I open it again, the title in the window is still “DEVONthink Pro”!

Any ideas on getting the new name to stick?
