Borderlands 3 cannot save when wine ge, cannot import save when using proton ge

Like the title says, the game worked just fine when using the appimage ver of Heroic with wine ge but had to switch back to flatpak as Batman AK wouldnt run with the flatpak ver. Heard switching to proton ge fixes the issue but no save files are detected when using using the save file download feature and even manually importing the save file to the prefix. When using wine ge the save sync feature works but game complains that it cannot save.
