Two small bugs in AX 2012 RTM image

Working on the AX 2012 RTM image today and found two bugs.
1. When to post and print PO proforma/confirmation, get the following error

To fix it, go to Procurement > Setup > Forms > Sorting parameters, remove UNKNOWN 

2. When to invoice PO, debugger pops up. Commenting out the assertion line in VendDocumentLineType - VendInvoiceInfoTable should do it.
