Purchase Order Not Using Cost From Selected Supplier

[VaporPhoxxe]

When entering a purchase order and selecting supplier, the item cost that is listed is only from supplier 1, not from the selected supplier if there are multiple suppliers listed in the product screen/ordering, with different costs entered for those other suppliers.

If you search by a supplier you will only see that supplier and won't see other suppliers.
If you search by a description you will see all the options.
