Vivoactive 5 Golf GPS Wrong

I had a VA3 that I used for golf all the time and it was great. I just got a VA5 and in the two rounds I’ve played, the distances are off by 10-15 yards compared to my Arccoss app or range finder. It’s been long and it’s been short, always by 10-15 yards. Anyone have a fix for this?  Do I just have a bad unit?
