dragonslayerxxx: I just bought myself copies of The Ultimate Doom, Doom 2 and Final Doom. Everything is in order but main page for first title seems to have a little icon (not sure what it is) that offers me to choose from The Ultimate Doom and Ultimate Doom, The ?
Second option doesn't offer any new files or installer so I'm left wondering what the hell it is? I thought it was Thy Flesh Consumed episode but the wording is, like you see, weird.
Does anyone know what it's supposed to be? Maybe a launcher bug? Screenshot down below.

Vampyr78: It's just way to choose how the name is supposed to be deisplayed in launcher. Games are sorted alphabeticly so if you choose The Ultimate Doom the game will show under letter T and if you choose Ultimate Doom, The it will show up under U.

FlavioV: I reported this on Mantis (cogwheel > Report issue) a while back. Never got an answer but the duplicated entry eventually disappeared from my library.

dragonslayerxxx: Not familiar with Mantis but did report to GOG support. They directed me to Doom 3 topics and after I said it doesn't have to do anything with Doom 3 they just sent me an empty e-mail with option to close a ticket. I've asked on reddit but nobody seems to have any clue on what it is.

FlavioV: I meant the Galaxy issue tracker. It has a web version but you should report this issue from Galaxy itself so the logs are attached automatically.

1. Launch Galaxy (if it's not opened already)
2. Cogwheel > Report issue
3. Fill the form and submit it

You might not get an answer (I didn't) but check back in a few days and the duplicated listing should be gone from your library.
