That seems unlikely. JRemote only has one writing MCWS call, and its only executed specifically when you press the "Save" button on the metadata view.
In any case, without being able to reproduce anything, I can only guess, and guessing doesn't get me anywhere.
Are you actually connected to the server, and controlling a client zone from there, or connected to the client?
Please always be extra precise when reporting bugs and explaining your setup. I cannot guess or remember everyones setup, unfortunately, and what I cannot reproduce or at least understand, I cannot fix.
