Using 22.8.28.334 - I have just run into the same problem. I entered, by mistake, 40 receipts when they should have been payments.
There used to be a simple toggle to change this in each transaction. The current “Copy to Payment” solution is excruciating. It does not copy the date, nor the bank account from the original.
Every transaction that I changed involved the following:
click to open transaction
click to copy to New Payment
click to change date
click to change bank account “Received From”
click create
click breadcrumbs to take you back to the list
click the Edit of original erroneous transaction
click Delete
Click “are you sure”
x 40 !! Is there a better way
