C2000 toolbox - Using High Resolution PWM and High Resolution DeadBand help

Hello community,
I have the launchpad F28379D, and I want to create PWM waveforms of 1MHz, with duty cycle of 50% minus the dead time.
Unfortunately using the simuling coder, with Active High Complimentary setting in the dead-time, my resulting pulses are not symmetric (dead time = 25ns). Instead of symmetric gaps between EPWM1A and 1B, their dead times are unequal, plus they don't have the 500-25 = 475ns pulse width I was expecting.
Below I'm attaching my PWM settings (dead time is 25e-9 from input source, CMPA is 50% from input source) , if someone knows what I need to alter to get this to work I'd be very grateful.
