Is there a way to always open Google Drive shortcuts from the same account?
Try deleting the shortcut and re-creating it. When you create a shortcut it should ask you which account to use before you select which file the shortcut should point to.

I had a similar issue on my LG G4 where it always asked which account to use. I think it is because I created the shortcut using a Google account that I subsequently removed and then added back on to the device.
