Impossible to plan a XC Ski workout and do it on the watch

I don't know if this is an issue with Garmin Connect (both app and web) or a problem with my new Forerunner 945 LTE. Previously (a couple of days ago with an FR745), if I planned a workout in Connect using the "Custom" option and started the training on the watch, I could select the XC Ski activity profile for the workout. Now the watch only lets me choose between Navigate, Tracker, Map and Other. Where are the other activity profiles? I can no longer plan complex workouts for my rollerski sessions... :-(
