Both albums titled “One Love” respectively by Bob Marley&The Wailers and David Guetta have been merged by Roon. When I perform a search for Bob Marley in my Roon library, his “One Love” album won’t even show. I found out instead that the “missing” Bob Marley album had gone under David Guetta’s name with the album cover of the latter’s One Love album
It looks like something in the file tags resulted in these albums being merged. You can correct this with the instructions in this Help Center article
You’ll need to separate either the David Guetta or Bob Marley tracks to a new disc using the instructions in the article. Roon will attempt to identify them. If it cannot you can do that manually.
