Yep, those would be the ones. In that screenshot, all were unchecked. Checking one turns the entire box green and the checkmark white. In other places, sometimes only the checkbox changes. It varies by app, with the Gowalla one being the worst place for them. On a light background, they are even more deceptive. Add in some bad lighting situations like bright sun, and it's near impossible to tell at a glance what state they are in.
