Trouble with correct yardage on my S20

Can anyone help? My golf club some time ago added 3 new holes. They filled out the correct forms for gps updated. I have a garmin S20, I used garmin express to update golf courses. The update worked a couple of times, then for the three new holes it went wrong. The nearer I got to the hole the further away my watched was showing. I updated a friends garmin (not S20) his is working fine. Other members have S20s theirs work. Been in contact with garmin support, for some reason they do not understand the issue, they keep sending me the basic trouble shooting remedies. I do like garmin this my second watch. But for some reason I cannot get help from support. So reaching out. It’s frustrating having to as the distance. The other 15 holes the watch works fine.
