AR Receipt actions are all disabled

Our client has requested to close all open balances, including both transactions and receipts. We successfully closed all balances except for some remaining receipts. For these specific receipts, all actions (including Application, Reversal, Deletion, and Refund) are grayed out.

Upon investigation, we found that the receipt status for these 8 open receipts is listed as "Cleared".

We are seeking guidance for any AR-specific configuration or restrictions that may be preventing further processing for these receipts.

Your assistance in troubleshooting this issue would be greatly appreciated.
