TTE and TTR datafields not showing on Garmin 1030

Have downloaded a number of xert datafields to my garmin 1030.

MPA, Power seem to work fine. However, TTE and TTR just sit there with no numbers? have loaded and reloaded. Changed password, etc but no joy from TTE and TTR.

Are they supposed to work?

You need to configure the fields to show what you want during a ride.
For examples, see More section at this link –

Also make sure you authorized each field with your Xert login as detailed here –
