This happened to me. Change payout split percentage on my accounts page, and then double checked the up and coming payouts on the Payment History page and it would not forget the previous settings. No amount of fiddling with it, delete, retry etc... would change it. I reported the problem to Host Support and told them to freeze the payments until the bug was fixed, but after being ignored and not paid for over a month and talking to numerous Agents, one released the payment and the incorrect percentage splits were sent out. I can't get the money back and I want to be compensated for the amount I was shorted. They continue to ignore me. If I treated my guests like this I would not be a Superhost that's for sure.
