Add-on: Ceon Manual Card 2.2.2

The credit card used was MC 4111111111111111 12/12

The invoice copy that was emailed to the customer and the email that was sent to the Admin did not contain the leading four (4) digits.

Credit/Debit Card

MasterCard XXXXXXXX1111

On the screen checkout (3 of 3) the leading four digits are displayed properly as '4111'.
On the Invoice copy found in <Admin>, <Customers>, <Orders>, order # 207115-blah, the leading four digits of the credit card are present.

Why are the leading four digits truncated in the emails?

I do not know if this is a Zen Cart email rendering or Ceon.

This is a manual cc process. I can't go to Admin to retrieve the leading four digits on every transaction.

Where can I start looking? I am in the process of uploading fresh code now. But I don't have high hopes there.
