Selecting OE Order for Billing on Items with Serial Numbers

In Macola ES version 7.6.100 I am trying to select an OE order to bill but am running into issues. When I go into the billing screen I am selecting the second option once we get to the line item portion of the screen which is ‘Bill Certain Items.’ The original order I am trying to bill for is for a total of 16 containers, and thus far 10 have shipped. When I pull the line item up on the screen, I can select it no issue at all; however the order is wanting me to select 23 containers rather than just the needed remaining amount. I am confused how or why 23 serial numbers are allocated to this order, when the total order was only ever for 16.

I found this documentation and completed it in a variety of manners and still not able to finish billing this order.
1. Open the order in the OE & RMA / Billing/Picking/Shipping / Billing / Select orders.
2. When prompted: “Order previously selected. Do you want to reselect it? “click Yes.
3. When prompted: “Clear Previous selections?” click No.
4. Edit the line items and review the Bin or Serial/Lot records. Delete the Bin or Serial Lots assigned to the items then reselect them and save the order.
5. Use the OE & RMA / Billing/Picking/Shipping / Billing / Unselect orders to unselect the order.

In the above steps I have tried completing them in a variety of manners:

- I have deleted all the bin/serial records assigned to the items and then just reselected only the remaining amount of items needed to fulfill the order and that didn’t work.

- I also tried it where I deleted all the bin/serial records assigned to the items and then reselected all of them over again, which also didn’t work
Any suggestions or throughts??

Thanks!
