You have a profile, named "MyProfile" (if you haven't named one - ever - it's "Default").
Change to a new profile that does not exist yet and select the copy profile option.
Choose "MyProfile" as profile to copy from.
Unfortunately it will not work as the component that is supposed to handle your
profiles (LibRockDB-1.0) is bugged at the Copy Profile option.
There are several reports on forum and jira about it.
