Project ID is Changing PO Charge Account

Summary:

I am unable to add a Project ID to my PO through a change order without getting an incorrect Charge Account

Content (required):

The requester used the wrong Charge Account on the req line and created a purchase order with that req. I am able to change the Charge Account to the correct distribution combination, but as soon as I add a Project ID, the Charge Account defaults back to what was on the req. I tried creating a second change order after first updating the Charge Account, but I have the same issue. Is there a way to change both the Charge Account and add a Project ID on the purchase order?
