What I see is that you're trying to reinstall a second instance after searching for "sonarr".  I honestly never tried doing that.  Does it work for you if doing this from the "Installed Apps" section?  That's how the system is actually designed to work.   But, now that I can see what you're trying to do I can fix or disallow that operation unless you're within installed apps ( have to look at the code tonight )   EDIT: Thank God you were trying a rather generic search term.
