Try an action of the type "Guess value"
Source format: %album%
Guessing pattern: %albumartist% - %dummy%

If you want to MOVE (and not copy) "Bon Jovi" (and others) to ALBUMARTIST and leave only "Essentials" in ALBUM so that there are no redundanccies, then try the following
Guessing pattern: %albumartist% - %album%
