Explore data fails to appear on Fenix 5x plus after sync

I've created a number of routes and waypoints in explore. My watch is paired and connected and appears to sync both ways ie it says Syncing from and to my device. However, there are no courses under the navigate app or any waypoints from the devices perspective. Where is the data going and why can't I see it. Oddly tracks on the device created are being sync'ed to explore. Help...
