2 codes in the same Steam account

[mecachisnacho]

Good night:
I am the holder of two licenses for the game IL2 Cliffs of Dover, one is in Russian, yuplay.com buy through the portal, and the other is a collector's CD version of the game physical. I made the mistake of installing both versions on the same Steam account.
Now I have the install problem that always puts me first install the dialogues and the version in Russian. I tried everything, UNINSTALL all and install only the European, but when upgrading from any patch, I put it all over again in Russian.
I tried formatting the computer even if you remain hidden files on my system, but even install only the European version always ends up showing the Russian.
Could I have a solution to stay only with the European version (Spanish) please?

Thanks
