The machines were just quickly swapped from the old coaches onto the new this morning, hence why they're not showing the new fleet numbers. The machine on 7150 hadn't taken the update with the new numbers yet, so they've just chosen the closest number in the list for that one.
Serves me right for not double checking and assuming instead. Was 6150 tracking in error?
