Two tabs, two clip to's, and lost database

Somehow in one of my upgrades I have managed to create two Devonthink office pro side tabs, two clip to icons on my Safari bar. I also can’t find my original database. The program loads a version with the same structure as I created, but with only a few entries.

I only have ProOffice 2.3.2 on my computer now. How do I get rid of one each of the tabs and clip to icons, and where are the Devonthink databases stored? I looked in Library > Application support, but there is no Devonthink folder.

The extension is in ~/Library/Safari/Extensions. Shutdown Safari before deleting it.

Your databases have .dtBase2 extensions. You can search for them with Spotlight or a utility such as Find Any File.

Thank you.
