Non-Inv items auto filling Target Subsidiary line field with incorrect information.

We've created intercompany purchase ordered and the non-inventory items on all of these similar orders are automatically filling the target subsidiary field.

Not only is this the wrong subsidiary (the vendor subsidiary not the customer) but when I change it to the correct or even blank option and save the record, the page will reload and all of them will reset back to the original.

If I try to save the record in any way and these fields are not set to the correct subsidiary or blank then I get the error: 'This Purchase Order cannot be associated with an intercompany entity and used for Cross-Subsidiary Transaction. Please remove association to the intercompany entity from this Purchase Order or uncheck the Allow Cross-Subsidiary Receipt checkbox for this Purchase Order.'
