When going to View payment and doing a search you are given the following different list. There is no way to select and search for the DCARD - Debit Card or CCARD - Credit Card options.
<option value="DD">Direct Debit</option>
<option value="CASH">Cash</option>
<option value="CHIP">Some Other</option>
<option value="BACS">Bank Transfer</option>

These lists should be the same.
Also if you edit the payment to change the method you only get the first list, even if you have entered it as a bulk purchase and selected something on the larger list.
