This is a change that they are working on! 10k is from the old high scores table, and they are working on moving more things to the new high scores table (like the message on the webpage said for years) so that might happen and it's not a glitch. I am not sure exactly what they will do once they get them all changed over but I just wanted to let you know this is intentional.

Welcome :D locking this up as it is not a bug.
