Price Breaks on Non-Inventory Parts

We are running Vntg 5.0 Patch .350. We seem to be having problems
with Price Breaks for non-inventory items pulling into PO's. The
parts are listed under Price Breaks for the particular vendor however
the prices either will not pull at all, or the price will be
incorrect. Anyone having any sorts of issues with the vendor Price
Breaks?

Thanks!
