Only have option to put Minion add-ons in drive not on PC

[Fenraur]

I'm trying to change the path to put the Minion add-on files in my Eso add-on folder but Minion will only allow me to put it in my drive and won't allow me to manually edit the path only browse and choose a different spot in my drive. What's going on and is there any way to fix this?
