Approach s40 duplicate rounds.

I have recently purchased the approach s40 and previously had the approach s20. Every round with the approach s40 gets duplicated whereas with the approach s20 it was not. I set scorecard Sharing to 'not now' as I saw that suggested but all that is happening now is if I try to click on the duplicate round I get an error message saying "something went wrong" I now can't even delete the round but that didn't work before with the duplicate anyway. I really don't want a duplicate round every time I play and it's only since I change to the s40 so it must be something to do with the watch? Is there a fix or a different setting I need to do? If not I'm just going to return it and stick with the s20.
