How to Unfreeze Receivables Transaction?

on fusion and I'm using seeded roles Accounts Receivables Manager and Accounts receivable specialist still not able to see complete as well i can see freeze option instead of complete once we do that we are not able to delete the invoice, Do you have any idea how to unfreeze Receivables Invoice.

We have created a AR Invoice with a manual source it in incomplete status but now we are not able to delete it, Allow transaction deletion was enabled in receivables system options. I tried with seeded roles still Complete and delete were grayed out any idea on this?
