TMC 2130 sensorless homing retest issues

I've enabled Sensorless homing on the TMC2130.  The motor finds the end and moves back for the retest perfect.  But with the retest the motor hits the end and grinds for a second before stopping.  I've tried increasing the reduction factor, decreasing the reduction factor, setting the back move to 20+, changing the sensitivity.  Nothing works.  It feels as if the retest has sensorless homing disabled.  Setting the back move to 0 does work, by disabling retest.

My hypothesis is sensorless homing is disabled during the retest.  Is this possible?  Is there a buffer time where two homing events can not occur less than x seconds apart?
