Hi,
I'm using the most simple configuration fo PMM since few hours (just config.yml with Plex/TMDb info, and 1 library with basic lines present in the wiki.
PMM create some IMDb collection (popular, top 250) and applied an overlay on all top 250 movies.
I tried to remove the overlay by putting "remove_overlays" to true but logs keep saying "No Overlays to Remove for the Movies Library". So I'm kind of stuck with the "IMDb top 250" overlay.
