Prior Month Receipts (Prepayments) and Automatic Cash Receipts

We are having issues with the prepayments created in Month A (when the invoice does not exist) and automatically matched in Month B (when the Invoice is created), the close date of the invoice is showing the GL date of the receipt (created in month A), so the AR reporting is creating wrong data. The processing option Override GL date on program R03B50 helps to fix this issue. Still, the receipt must be posted (system designed), but this is creating an issue with the Automatic Match process because R03B50 applying receipts to invoices is creating unposted transactions, no posted ones,
