System generating duplicate sales transaction numbers between sales receipts and invoices

All of sudden, the system is generating duplicate sales transactions treating Sales Receipts and Pledges/Invoices as a separate and independent #. example: if the last sales receipt is x218 and the last pledge is x216, QB will only let us generate a pledge as x217, even though there is a sales receipt already as x217. And then we end up with multiple payments for different items on the same sales transaction. We are Live Experts subscribers, but they are unreachable for call back yesterday and today. Have others had the same problem. This just started. And on Sunday, the option to change the # on Sales Receipt was gone, but Monday it is back. So that is work around for Sales Receipts, but we can't do that for Pledges. Any solution? Also, we have several duplicate sales transactions now. how do we untangle that and not screw up inventory and credit card transactions/deposits accounting?
