Temperature unit display

Good day for all,
We added a new thermocouple to our MarkVe (migration from Mark V to MarkVIe) panel, in configuration all the thermocouples are displayed °F in tool box and °C in cimplicity screens, we did the same for the new one, the problem in HMI screens (Cimplicity) the new themocouple is displayed in °F.Can some one tell us what is the problem.Thanks.
