Thanks for understanding.

The messages from others may seem a bit heated, but that does tend to come from recurring issues with users of the same software you are using. It's a pain point for a number of mappers.

I'd definitely encourage trying to push the developers of the software you use to correct it to handle golf courses as they are meant to be mapped, or to be able to take a .osm file in like other software can (i.e. Farming Simulator map makers), that way you can download an area in JOSM, make the changes you require, and save those changes locally for the software to use, instead of uploading to OSM itself.
