Can’t see the maps in downloaded courses

So after sending the course to device, it’s showing under ‘courses’

but when I hit ‘do course’ I get no map, it just starts a regular workout

ive tried switching on and off and syncing after downloading, the app says the course has been sent, I get the green tick, the course appears on the watch but it ain’t there?

the courses that I’d downloaded previously are still there and display the maps correctly but anything new just won’t show
