Trouble Interpreting MCC DVD+R scans

I have run af few Krope2 test of my Mitsubishi DVD+R’s, it seems everytime I scan them I get this single extremely large spike, PO values up to 160.
What should I make of this and could this be a problem later on in some readers ?

I think it is just a quirk with the DVD-RW you are using to do your scans and not a problem with the disk itself or any indication of its write quality. In my opinion, you don’t have anything to worry about: they look like pretty good burns!

I thought so too at first, but the problem is continuing, and its only these discs not other brands and its always only one spike.
It just seems very strange.
