Receiving error when trying to import CoA


HI, When I try to import me CoA into a new Sage I receive an error that says "Default purchase ledger must always be visible"

I have been those settings but as far as I can see, it is visible.  What makes this even more confusing, row 14 refers to the stock control account

Again I have looked at both the purchase ledger and stock settings and I can't see anything thing that looks wrong
