Rapid Position settings trip limits

Using build 364, I am seeing that my XXL: keeps hitting the LH rail when using the Rapid Position settings. Upon review of the log, CM is sending the command to go to position 840. In my case, and I suspect others, we need to set the X extent to be about 838 in order for it to not hit the rail. As such, sending the command trips the limit (if you have soft limits set).
