how to delete golf courses of vivoactive watch

You don't delete them from the watch. You download them in the Garmin connect app and when you go to golf on the watch it pulls up the list of all that you download on the phone. When you choose one that one is downloaded to the watch and when you end the activity it is removed from the watch. You can download as many as you want in the phone app. 

Hi my watch only takes 5 courses , so I had to delete the courses on my phone(sliding them left) and then downloaded the new ones on the phone. I then had to transfer the new courses over.

 thanks 

this doesn't work on my watch - it still has courses I haven't I played for months / years even tho  have removed them from Garmin connect. Need some assistance please

I have exactly the same problem will not delete by sliding to the left so unable to add new courses as I already have 5 on my watch. Any advice?
