TIM1 PWM BK and BK2 strange behavior

Hello,

I configured TIM1 as shown in the attached image:

Everything works as expected

I am controlling an inductive load which oscillates heavily after the PWM is turned off. I therefore decided to immediately short the low-side MOSFET (CH1N) to ground if a BREAK or BREAK2 signal is received. I set the Channel Idle State to SET. And the behavior of BREAK/BREAK2 changed.

As seen in the close-up::

A low state on BK2 does not set a high state on CH1N. Should BK1 and BK2 not be ORed?
