Jason,
The Block Tree is designed to display not only Big Y matches (it appears you don't have any) but also certain Y-STR matches who have taken the Big Y test. ?I suspect this is what you are seeing.
If you look among your Y111, Y67, and Y37 matches these two men should appear there.
Most people will receive absolutely no benefit from uploading their raw Big Y results to 3rd party sites, and I generally don't recommend that people worry about it.
