This is not a bug, it is by design and won't change.
It happens when garbage trackers like rarbg rename things for no reason and do it incorrectly 99 percent of the time.
sonarr trying to change this. and bigest % of user using rarbg. its also happend to me 5 times in a month (not so good for automatic program)
its fixed in sonarr https://imgur.com/0SUYsUw
markus added a change to ignore it, so i will pull in the same change.
also, an automatic program is only as good as its data. rarbg is garbage so you get a garbage result. simple as that.
