Simscape Full-Bridge Error

I'm using a PWM generator as the gate signal for the full-bridge block. I want to simulate a single phase full-bridge inverter. I'm getting an error that says since the pwm generator has an 8 pulse output and the converter block is only 4 pulses, it won't work.
Can someone tell me what I'm doing wrong and how to simulate a single-phase full-bridge inverter with this block? (The example is no help)
I've attached a few illustrative pics. Thanks!

Hello Ryan,
you are using a PWM generator designed for a 3 level inverter. This is a 2 level full-bridge. Please use the 2 level PWM generator, and select the appropriate topology (it will default to a 6 device inverter, but can be set to work for a full-bridge).
