Installing a specific version of a GOG game (The Witcher 3)

Hi everyone, this is my first post on this forum.
I’ve read the pinned thread and I’ve tried to search before I post.
My problem is the following : I own The Witcher 3 (Complete Edition) from GOG. I installed it on my Steam Deck through Lutris with no issue and it automatically downloaded the version 4.03 with the french voice dubbing.
What is odd is when I wanted to install the game on my desktop computer (gentoo, up to date) it wants to install the version 1.31a of the game.
I’ve tried to download the installer from the GOG website, but strangely, I can only either go for version 1.31 in french, or version 4.03 in english. I’ve tried to install version 4.03 in english and then copy the audio files from my steam deck and it sort of worked but about 5% of the voices were missing so I don’t think it’s a good solution.
So my question is : do you know if there is a way to force Lutris to download the right version of a GOG game ?
Thanks in advance.
