Inventory not displaying

I’m a bit confused. I created a usergroup called “approved customers” while keeping all inventory visible to guests. As an admin, or when not logged in, I can see everything on both the front and back end, so I never noticed an issue before. However, when I log into my vendor account, I can’t see any of my products on the frontend, though the backend everything is there. Preview is fine, too. With the standard Multi-Vendor setup, I have no way to change what usergroups a vendor admin can belong to. I only just noticed this recently, and while I can still see everything as an admin, it’s still frustrating.
