Having trouble with the retrofit alarm kit...

I’ve noticed odd behavior at some of my wired zones… And it is inconsistant, maybe only happening 10% of the time.

Starting with the zone closed, I’ll open the door/window… The zone shows open as expected. Then when I close the door window, ocasionally it seems like it is quickly registering as closed,open closed… I know something is wrong when this happens because I hear a chime when the opening is being closed.

Even more annoying is that sometimes the door/window is stuck saying open and I have to cycle the door/window a few times to get it to show as closed.

I used my multimeter to check the connections, and all looks fine from what I can tell. Close to 0 ohms when the door/window is closed and ‘infite resistance’ when the door/window is open.

I even tried to add a 2k ohm end of line resistor to the end of the line to see if that would help. It didn’t…

Wondering if I have a faulty retrofit kit (doubt it since I have 2 and they both exhibit the same behavior) or if there is something funky in the software?

It is also worth noting that I have 3 main doors that use recessed contact sensors. Never seen a problem with these. All my windows and a sliding glass door use surface mount contact sensors. I am only seeing problems with the surface mount sensors, but again they seem to function fine when tested with a multimeter for resistance.
