Odd behavior of stickon wall switch, help!

[Frankenberry]

I have 3 stick on wall switches in my kids room (1 at the door) and 1 next
to each bed. I have three lights connected to 3 lamp modules numbered 2,3,4.
I also have a transciever with nothing plugged into it. All of these are set
to house code G.

The 3 stick on switches are programmed for house code G and to start at
number 2, thus controlling House code G units 2,3,4.

This all worked fine for awhile, but now only the top button on the the
stickon switches works with the lamp modules.

So in a nutshell only lamp 2 will turn on and off.

Adding a strange twist to this, the non working switches (code 3 & 4)
control a set of lights on my A house code!

Any ideas why this would/could happen???
How can a "G" device control "G" and "A" devices?
