I reckon a full reset and update is worth a try. Not suggesting this has anything to do with it, but I notice on the screenshots you have the language set to American as it says "Postal Code" rather than "Post Code" so it's possible that a good old fashioned reset and start again might yield a better response. I assume it is a UK/Europe unit?
Also, I'm damned if I can figure out where the setting might be on my XT, but your temperature is also showing in F rather than C. I can't see a way to change that so it's almost like your device thinks it's somewhere else or the mapping is for somewhere else.
