I received rejection 'W95: Related Previous CCN-House Bill Close message cannot quote a paper related House Bill CCN'. What does it mean?

Reason: Master freight forwarder (Previous CCN) did not file eHBL and filing was done via paper.

Resolution: Advise no need to file the eHBL electronically, best option is to cancel the accepted eHBL (W95 is a Close Message rejection) and filing should be done via paper process as well.
