Vermeer 605M Netwrap issues....

We have a 2008 Vermeer 605M baler and we are having issues with the netwrap process.  Last year, we used it with no issues.  During the winter, we replaced the belts with a new set.  Now we are having issues with the net sticking to the belts in some places and eventually gets wrapped around the clean-out auger in the front above the pick-up.  It wraps around where the pieces of rubber belting are mounted and coincide with the shorter 522" belts.  We have sprinkled corn starch and baby powder on the roll of net and on the belts themselves.  This will help, nut no alleviate the problem.  Would a dull blade used to cut the net be the culprit?  We have noticed that on the dumped rolls that the net end you can see is kind of rolled up and does not lay flat on the roll of hay.  Our speculation is that the knife is dull and causing the net to not be cleanly cut and once it completes the netting cycle, the ragged end is snagged up or spit out the front enough for the auger can grab it and removes (2) 1 foot sections of net back off of the roll....in line where the rubber belt flaps are mounted on the auger.  If the knife is the culprit...do we replace the knife or try yo sharpen it somehow??  Any other ideas and feedback is welcome.  Thanks!
