MCC Push-to-Talk not Applying After Restarting?

I have PTT disabled because my mic has a physical mute button on it, and is easier for my use case to use over using the in-game key bind for holding to talk. The issue is that it works if I apply the setting, but if I close then re-run the game, I have to manually enable PTT, save, then re-disable and save for it to work again. Has anyone else experienced this, and is there a solution? Is this a game-specific issue, or could this be attributed to the headset I'm using?
