Same issue here. It seems that Tropico 5 and Railway Empire (both games published by Kalypso) was merged into a new entry called Siamese. When I check, Galaxy shows that I have two copies of this game called "siamese". Also, Raliway Empire disappeared from my list of games.

This bugged me so much that I tried the following, all to no avail:
1. Wait a few days hoping it would update itself
2. Hide my game library in Epic launcher, then unhide it again
3. Log out of my Epic account in Galaxy, then re-login

Yeap, same here. Has anyone tried installing the game to see what it actually installs?

I installed the game just to see if the problem was solved, but did not solve the wrong name.

I redeemed the free game "My time At Portia" in Epic Games Launcher and GOG Galaxy shows this game in the library as possessed so the problem is related to Tropico 5 only.

But did it install Tropico 5?

It does but it still points to the wrong game.

Then it's only a cosmetic issue, which is better. it might trigger some people, but yeaah we live to suffer.

Oh, so its only a cosmetic error? Thats such a relief! thanks so much!!

Good news, it's been updated as the correct game now, even though it still has the Railway Empire description to it but good enough I guess. :)

Even though it now has its own separate entry, it still has a title of 'Siamese' and the description for 'Railway Empire'.

Therefore, searching your game library for 'Tropico 5' will find nothing. To find that entry, you have to search for 'Siamese'.

Hopefully this will get fixed, as I often search across my whole game library to find out whether I already own a particular game on any of the platforms before buying something I already own.

You can change the "Siamese" name with the edit option to "Tropico 5," which also makes it the sorting title findable by search.

Can confirm, it all looks a-ok! Thanks!

Crying suns (Epic), shows on Gog Galaxy as a game called Citrine.

I came here to post exactly the same. When you click on Citrine, it shows the correct information, including a description and videos/pictures of Crying Suns, but the title is still wrong.
