Vortex 'Manually Set Location' doesn't save selected directory for Days Gone.

[superluminati]

When I set up Vortex to manage Days Gone, it couldn't automatically find the game (likely because I have it installed on my D\: drive).  When it asked me to manually set the game directory, I accidentally chose the wrong directory.  The 'Manually Set Location' function allows  me to pick the correct directory, but it doesn't save the directory I picked, and unmanaging and remanaging Days Gone in Vortex doesn't  help, either, as it seems to remember the incorrect directory I initially selected.

I can't find any posts about this issue, and I'd be grateful for any  ideas as to how to fix it, thanks!
