Fenix 6

Good day all, First I have a Fenix 6 pro, but there no option for golf and fenix.... When I put my score Hole by hole with my  garmin fenix 6, for a 18, that give me this (picture)

Why I have the total score of my 18 on the first 9 and on the back 9 I have 0... its kind of anoying. Thanks for your help (everything is up to date). I try to put manually with my phone its work ok.
