ConnectIQ Data Fields not showing up on my Activity Data Fields list

hello, I own a Descent G1, and recently bought a Stryd Pod to record my running data.

when I go to the ConnectIQ app (and Garmin Express on macOS) > download the Stryd Data Fields > successfully install (they show up as installed and synced on the app), they still don't show up on my watch's Run and Treadmill apps' list of Data Fields..

I go to Activities & Apps > choose Run / Treadmill > choose Activity Settings > Data Screens > Add (new Data Screen) > and when i go to pick a field, the ConnectIQ Data Fields are not on the list

only: Timer, Distance, Pace, Speed, Heart Rate, Run Dynamics (I have a garmin running dynamics pod), Cadence, Power, Temperature, and Other...

I have tried adding other Data Fields through ConnectIQ beyond Stryd's, all compatible with Descent G1.. so not sure if it's a watch problem?

I have the latest firmware, I have reset, rebooted, re-installed, several times... nothing works...

any help, please?
