Just came on to report this same bug, and I see it's already reported. But yeah, same issue here with multi-round tourneys.
Here is the latest reply received from WGT Support.
It is just a display issue and the players are not being compensated for the finish.
There is a known display issue that Q/A team is working on where Multiround tournament leaderboards are not displaying placement correctly. Players that missed playing rounds will show 0 for that round and its making it look like they are in first because they have a lower score (0). Q/A said that they can't get it fixed for this release, but it should be hopefully fixed next release.
