EDIT EDIT: Nevermind. I figured it out. Switching to toggle in the button. I don't understand what the Momentary is good for though, if anybody wants to enlighten me.
From what you described, I think you're seeing a double trigger from it sending the "0" (off state) when the momentary button is released. The settings you want for a button I think are "Momentary" and "Don't Sent Off".
