Cytron Mod Not Working

I am using a cytron MD 13S and I did the Cytron freewheel mod, however the motor is still backfeeding. I have done this multiple times before with no issues, however this one won’t work. I even tried a new Cytron and did the mod again but the motor is still backfeeding. Also, the test buttons work on it still. And, the original Cytron was working and would freewheel, but then suddenly quit and then stopped working. I am at a loss. Thanks for all the help.

Maybe post a picture and someone might see something
Off the top of my head it sounds like the pwm2 pin isn’t shutting off
