[Elecraft] SSB Filter Flatness anomaly

I have been working on the filter flatness modification and have come across
something that does not seem to make sense to me.  The filter response only
looks like I would expect in the 'wrong' SSB mode.  That is things look
flatter in USB than LSB on 40 meters and LSB is flatter than USB on 15
meters.

For those who need a picture, go to

Does anybody have a clue as to what might cause such an anomaly?
