You need to work with the author of your tool to implement a fix on their side. OSM has strict, well documented, standards on how to map everything from roads to golf courses to zoos. This isn't an OSM problem, it's a golf simulator problem.

This is a long standing bug that they are aware of. There is even a fix that has been proposed that hasn't been integrated yet. See https://github.com/chadrockey/TGC-Designer-Tools/pull/143. Maybe you could add your voice to the pull request asking it to be incorporated. If you're technical enough, you could pull it yourself into a private version of the tool and run your own fixed version.

Breaking golf courses in OSM and causing others to have to clean up after you will likely result in a ban. And honestly, none of us want to see that happen. Thanks.
