I stumbled upon a problem where games from Epic Games Store aren't being detected correctly. Had two games where they are detected as another game. The first one is the Saints Row Boss Factory got detected as Sonic Mania and the second one is Car Mechanic Simulator 2018 got detected as City of Brass. I tried renaming the incorrect games yet it also rename the legit version of those games. Sonic Mania was a free giveaway on EGS and City of Brass was bought on Steam. I was wondering if anyone else has this problem and is there a way to fix it. It'd be cool if there's a feature to rename individual duplicate in case something like this happened.

I'm having the same problem with CMS18 showing up as City of Brass.

Same issue as well.

Same. CMS18 showing up as City of Brass.

Same,
for a moment I thought someone was accessing my library because it said I played it 5 days ago,
and I was certain I didn't play City of Brass.
Then I started the game from GOG Galaxy and realized it was being reported incorrectly,
Car Mechanic Simulator 2018 was launched and that finally made sense.

Same problem here. This has happend before with other games from EGS, but usually it got fixed quite soon...

It seems GOG allows to change the name manually as well as the game details such as the cover, icon and the backdrop picture. This is one way around the issue. Automatically generated content such as the videos and screenshots will remain unchanged, though.

Please shout out when the problem is resolved.
