Hello Garmin,
there is a bug constructing the workout page for indoor activity profile even the GPS mode is off.
Menu -> activity profiles -> data screens -> workout : no possibility to change number of data fields or remove them at all.
Addtiionally there is no possibility to remove 'step distance' [m] data field or change/replace by stamina. The step distance during indoor training is useless.
That's a bug, I think.
Regards,
