[help] lutris won't let me remove a drive from the game prefixes

I've set my sd cards to mount to a folder in my home directory and pointed the default installation folder of lutris to that directory, so when i swap cards lutris reads the games that i have on it, but now every game has a d: drive that points to that folder, when i try to change the path to a folder placed a level deeper or when i try to remove that drive entirely, after i close and reopen the wine configuration panel it reappears. Is there any way to prevent lutris from changing it back? I have the same setup on my laptop with linux mint and the same version of lutris and it doesn't happen, so I'm at a loss about what could be the problem.
