As with the issue noted in another recent thread in this forum, there is a bug with the numbers shown on the post game leader board for all distance related records.
The number shown is labelled yards but is in fact the metric recorded distance, eg: I just played The Links at Royal Nuuk, my longest drive in game was 315yards but on the post game leaderboard it is shown as 287.9 yards which is in fact the metric conversion of 315 yards, I also saw this with my longest hole out, in game, I holed a 9 yard chip, on the leaderboard it displayed my longest hole out as 7.9 yards which would be correct if it said metres.
I am playing on XB1 and have my game settings set to imperial.
