having a problem with technician notifications

you can see from the pic here is what I set our notifications to

after a little while, maybe 20 min, I will notice that emails dont seem to work right and when I check, it looks like this

notice the lack of quotes and the re-order of names. When this happens, only Joe and Andy get emails, Jim does not. 

If I re-pick the technicians, it works again for a bit and then resets itself again

can you help me make it stop changing?

thanks so much
