When I click "view all" on the level leaderboard, it shows some different times than the actual leaderboards do. Why?

I honestly don't know. That's something I noticed recently and have been trying to figure out. It didn't used to be that way. Both "view all" and the character specific boards used to show all the times. Could be some sort of site glitch that makes them hidden on specific boards. This only happens on the times for version 9b for some reason.
