This September payout is not finished yet, what you can see is the held amount from US2 and EUN1 satellites, returned as a second transaction last month:
The Stat will be updated when the payout will be finished. Before that you will see an estimation under the last month in the usage above a Payout History. The Payout History for September will be updated too after payout is finished, if your node is eligible to receive a payout (cleared a Minimum Payout Threshold), otherwise it will update an Undistributed amount instead and it will wait for the next month for an another attempt.
