Error adding items to RFQ 'margin_type'

New installation of ERPNext, Every time I add a line item to a Supplier Request for Quotation I get the following error:

AttributeError: ‘RequestforQuotationItem’ object has no attribute ‘margin_type’
Possible source of error: erpnext (app)

capture

It also appears that item specific fields (item description by example) are not getting populated into the RFQ but hopefully fixing the error resolves this
