Why does the advanced timer PWM CH1 output affect CH2N?

WFan.1

This is my simulation output waveform.

They are CH1, CH1N, CH2, CH2N, CH3, CH3N

It can be seen that CH1, CH2, and CH3 are all normal, but the complementary waveforms will be affected by other channels.

How can I configure it?

I want to use multi-channel complementary and different Duty.

The following is my CubeMX configuration and wave type​

Which STM32?

What simulation? The simulator may be faulty, try real hardware.
