Thanks for spotting & reversing.

Is this a hole?
The course's website don't list it.

Hi
Please use the prow_ref tag, not name.

prow_ref=*

Hi
Is this really a tee?
way/965098921/history

Actually I meant a tee. Looks a little large.

Hi
Is this definitely a green?

Are you sure about this hole?:
way/996151051

There appears to be a tee/worn grass/fairway for it to the South East.

Hi
Please don't adjust or split the Cotswold AONB relation. It's location is officially set.

leisure=fishing

The 'modern' schema for all inland water features is now natural=water & water=river/canal/lake/pond etc.

On the actual water polygons, I'd use:
fishing=*

If this site is specificity for fishing, You may want to draw a large polygon around the site and tag that with leisure=fishing along with a name & any other relevant tags such as fee, opening times etc.

Hi
Are these actually canals?
Would the be better tagged as drains or ditches?
waterway=drain

Please don't delete valid railway stations. (different codes)

Please don't remove valid tags (station=subway)

Hi
Please don't add the conflicting landuse tag to golf features. It's meant to be used as a stand-alone tag not a sub/adjective tag, Surface is the correct one to use.

landuse=grass

Hi
Welcome to OSM.
All UK railway stations are mapped as nodes.
node/5077066091#map=19/52.88819/-4.41616

This building should be tagged as a train_station.

Hi
I note you didn't contact iccaldwell to ask why another primary tag, 'landuse' had erroneously been added to primary tag, 'leisure'. They conflict each other.

landuse=grass

leisure=common.
Half of this page discusses what's wrong with the tag & the main paragraph says how to tag it differently.

JOSM flags leisure=common as a error in it's validation process.

If the software you use is unable to cope with your expectations, may I suggest you contact the developers, or use other programs which allows it to function as you wish.
This is a routine I use, which you may find useful:

I contest it's not a "big edit". It's knowingly & intentionally kept within a single country. It neither crosses borders, oceans or continents.

Even as an Englishman I consider 'common' & 'village green' too quaint for OSM.

Hi
Please provide a specific link to an example that you've contributed?

Hi
What's a "riverine"?
way/916582044/history

Hi
You've tag a few waterway=yes in this area. Any idea what type they are it would be great if you could get them to render.

Hi
natural=grass is depreciated.
For meadows would surface or crop be better?
natural=*
