The gaps appear to be in the normal range and shows the windows need to be open a ways before they show trip.
The closed closed readings are higher than the other sensors, but by such a small amount that I would not worry about that. It may be worthwhile ensuring the wiring from the plug in transformer and the wires to the battery are secured (nothing loose, very lightly tug on them).
Other than that, I'm pretty much out of ideas.
Oh, one other thing...you are not using EOL resistors, do you have that proper setting in each zone (no EOL's installed)? I can't remember where that is at in the Elk RP software but its somewhere in the sensor type.
