I just checked out my Config, I had an off-by-one error.
L: Button 5
R: Button 6
EDIT: hold on, that might be a Mac thing.
Well here's the complicated way to get the buttons:
Press and hold BUT NOT ALL THE WAY on the left trigger (go until there is resistance). Then click on the L box and then press all the way down on the trigger.
Repeat for the right trigger.
This is how I got the correct layout. If this doesn't work, you have a bad controller/adapter.
