Yes, the ground glass is definitely out of whack. See if they will trade you a complete Pro or Pro TL for this body. Then you would gain removeable backs, removeable prism, different screens, different winders, etc. The Super would be good too, and it has a 1/60 mechanical setting in case the battery dies.
Heck, I would even trade it for a good 1000s. You can't change the backs, but you still get two (or three) winding options, several view screen options, and several finder options. They are like a tank, I'll probably never get rid of mine.
