Item expenditure date error when creating an invoice

Hey all, When you enter an invoice not matched to a PO and the item expenditure date is outside the project active date you get an error message:

However when you create an invoice that is matched to a PO and the item expenditure date is outside the project active dates you don't get the error message and allows the invoice to be validated and accounted. But fails to interface to project costing because of the item expenditure date is outside project active dates. Is this expected behaviour???

We are on R12.2.10
