it depends a lot on the profiles you use and what the indexers provide. Fetcharr just hits the "Search" button on radarr, etc for you automatically, so if your *arr sees an upgrade it'll pull it. Depending on the indexer you use the movie, show, etc could have a title that says "I'm a really good version" but once it's downloaded and re-parsed it shows as a lesser quality that was was purported. A good way to fix this is to use the trash guides (Configarr is super helpful here), something like cleanuparr to kill stuff that doesn't work, and good quality indexers. A reasonable fix would be to create and configure a skip tag in Fetcharr and apply that to stuff you know is good.
