On your Settlement report from Adyen you may see "Deposit Correction".
For reservations where funds have been captured but the guest is not due to arrive more than 14 days from the settlement date, the risk increases on refund requests, chargebacks.
Therefore Adyen uses an algorithm that covers the risk analysis and based on the outcome a deposit correction will be made.
This correction is nothing else than a situation where funds are taken but reserved until the arrival date comes in scope, then the funds are being released.
Please find a video that explains the deposit correction: https://vimeo.com/659247903
