Fenix 5x sync brings data from Explore Web but never says synchronized


I can get all data I create using Basecamp and import to Garmin Explore Web or creating directly at GEW to my Fenix 5x ( via Garmin Explore IOS) but no waypoints (saved locations) created directly in the watch.

In any case I always get an error sync message and the status is always "not synchronized".

Any ideas?

Thank you,
