The Steam game 'Penumbra: Requiem' doesn't appear in my collection in GOG Galaxy.

The other two Penumbra games ('Penumbra: Overture' and 'Penumbra: Black Plague') do appear in GOG Galaxy.

I currently have 'Penumbra: Requiem' installed, but if I go to the 'Installed' section in GOG Galaxy, it incorrectly tells me that 'Penumbra: Black Plague' is installed.
