Trainings suggestions, Garmin Coach, Synchronization

I had a training plan for cycling drawn up in Connect and have been doing these training sessions for some time now.

However, the Garmin Edge 1040 no longer synchronizes this, but displays the suggested workouts from the Garmin Coach. Even if I deactivate the Garmin Coach, these training sessions remain visible. The workouts from Connect do not appear in the Edge. Synchronization via the phone works, but always fails via the WLAN.

How do I get rid of the training suggestions from Garmin Coach?
