i had an experience with power bleeder having trouble bleeding air out. Use conventional up...down...up...down...stigma, which worked for me as it seems to push the air out with greater force.
also, other times, when the pads were not yet worn and seated to the rotor surface, i had some mushy pedal. few high speed braking cured this problem for me.
check all the hard lines and connections for possible leak somewhere else.
