PWM problem

Hi, We're working on a project involving control of a BLDC from Faulhaber (3564) with rather low inductance. When loading the motor (sensored, velocity control) a ticking sound appears. I tried to take a closer look at the phases with a scope and caught the following (figure attached):

It shows Hall C (green) and the three phases (A yellow, B blue, C magenta). When switching commutation state, phase B alone is on for a short while. It doesn't look right and I wonder if this could be the cause of the noise? And what can I do about it? The same behavior is seen with the BLDC-Sensored example project.
