The advance is always repaid only with those releases that are part of the contract. These can be old, existing releases, or new, unpublished releases. The repayment itself takes place automatically on a monthly basis. As soon as you have received the income from the corresponding releases on your account, it will be checked if there is still an open advance for these releases. If so, the amount will be deducted according to your advance account. If the advance is fully recouped, the income will remain on your account and you can withdraw it as usual.
