Fenix 6x HIIT activity on Connect app: data missing

I tried the new feature released with system software 20.30 update "HIIT activity profile" on my Fenix 6X Pro Solar with a 30 minutes premade workout.

After the activity, the app correctly sinchronized with the watch, but on the app sheets are missing some important data: there is no "load" value in the statistics sheet and there is no "training effect" data and graphs in the other sheet.

On the watch and on Connect online all the data is ok and visible, also in the Connect app graphs ( menu > training status > load > load focus - workouts load ) everything looks as expected.

Is that normal or is just a bug? It's just me? Fix incoming? Garmin knows? Thanks!
