Hi,

I notice you are doing a bit of golf course mapping.

The tag for a green is golf=green rather than grassland.

Golf holes use ref=<hole number> not name=<something>.

The centreline of the fairways should be golf=hole.

I have fixed the ones you've already done.  

For more details you can have a look at https://wiki.openstreetmap.org/wiki/Key:golf

Happy mapping.
