Lumber Yard is not working properly on this leg. It showed I was in the top 1% before I even played it, and when I did race, it seems to have taken my record from the global leaderboard and compared my run to this score.

I think Lumber Yard on Dakar Leg 6 is referencing the global LB, and not the Dakar specific LB like the rest of the tracks do. This is the case for quite a few people, not just me.
