Training Peaks and Power Meter

I use the automatic upload from Training Peaks to bring my daily routine plans to my Fenix 5x.

When prompted, I select the "Do Workout" option from the device. 

If the plan is set with Heart Frequency thresholds, everything works fine. I see the "odometer" for the heart, with thresholds and alarms sound when out of desired zone.

The problem comes when setting Stryd Power thresholds. The "odometer" just shows -- and no alarms.

Stryd is working fine, as I can see the power correctly shown in other display windows.

Any help? Thanks!
