Doug: To my knowledge, this is the first example of this. Clearly it's a Go4 issue so I would first make sure you have the latest version. I don't recall if you mentioned which OS your display is using but if it is an Apple device, even if it shows the latest version, delete Go4, do a reset on the phone, then go to the app store and download it again. I've had to do this twice in order to get get the latest version even though iOS did not tell me there was an update or, it showed it AS updated. For Android, I hope it's just as easy.
That's where I would start and I don't think it necessary to update anything else since the software is what controls that screen. Seems like you have an old file in your copy that Go4 is calling up for that page.
But, maybe one of the experts will have more help than I have to give.
