Window Sensors Flapping

I have a simple 6 zone system and my window sensors seem to flap multiple times randomly.  I've reconnected them several times and nothing seems to do the trick.  It's not just one zone either.  It's both Window zones.  I have them both set to "Open/Close" contact sensors.  They even work when manually testing.

I'm running everything off the alarm panel version 2, but right now, I can't arm the system at night because it will set off randomly with the window sensors.  When they change state, they'll do it multiple times for a couple minutes, then go back to normal.
