Need help rearranging episode order on a show

I have been attempting to correct the episode orders for the first season of "The Most Extreme". I can verify that this order is correct based on airdate listings on newspapers(dot)com, but every time I try to change the episode order, it gets rejected. The only thing that has been accepted is the airdates, which should be helpful. I should also note that the order/airdates of episodes 10-13 are correct and don't need to be changed.

Here is the correct order (excluding already correct ones):

Episode 1: Jumpers

Episode 2: Gluttons

Episode 3: Speed

Episode 4: Births

Episode 5: Cheats

Episode 6: Survivors

Episode 7: Builders

Episode 8: Horrors

Episode 9: Fighters

Thank you in advance!
