Rob,which unit is this? I may have to send you another one. It really doesnt effect anything but I may have missed that it did that as Ive had one like that and I couldnt figure out why or how to fix it for some reason. I used that one for parts. I always check all my units but either possibly I missed this or it just decided to go south. It will work fine in the meantime but Ill get another 1 to you and you can keep that one for parts.
