Getting "The uploaded file isn't a valid Web Connect file" uploading from the bank. It seems the problem is <CHECKNUM> tag in a transaction. Anyone else seen this?

The qbo file was downloaded directly from the bank. By trial and error I realized the only odd field out from previous uploades was a transaction with a CHECKNUM tag in it. I checked the OFX Version 2.3 specification and it does have CHECKNUM as part of the STMTTRN. Is this new or has quickbooks never supported that?
