3.3.4.0 Does Not Solve Power Spike and Dropout Problem on Flux 2

See attached screenshots showing both power and cadence irregularities with and without a separate BT cadence sensor.  Same result even if I use a separate Wahoo BT cadence sensor, so I think it is internal to the Flux 2 brake.  This always happens when there is a sudden increase in slope (like from 2% to 5% or more).  It does not help to shift early into a low gear and try to maintain constant pedaling, so I do not think this is cadence related.  I think it is torque related.  (Please ignore the pause about 1/3 of the way through the ride with the Wahoo sensor.  I stopped to make an adjustment.)

These sudden power surges are a bit of a knee buster.  This never happens on downhills, flats, or small uphill slope changes.
