A couple things jumped out at me. Since I remembered that you had the original post on the button controller issue with the same device, I jumped over there to refresh my memory. Then I saw on your last comment that you had excluded and repaired the switch. This might have been useful to include in your original description.
Then, looking at your photo of the Zwave details for the device, I noticed in the messages column that there were Zero messages. That should not be the case if you have been pressing the buttons (at least as I understand it).
It is almost as if the button controller app is calling a device that does not exist anymore. Or the device itself is just having issues.
How did you remove and repair? Did you use the "replace device?" Or did you just remove the device, and then repair it. Before removing, did you disassociate the device from all apps it was connected to? After repairing, did you reassociate the "new" device in button controller (and any other apps)? Or, is this button rule one you created AFTER excluding and including again?
