Hi,
None of the problems you are describing are to do with Ceon Manual Card.
The text "No Order Payment Data Available" is not part of the software, and the facility to delete CVV numbers is not - and never has been - part of the software either.
This sandbox of yours clearly isn't a fresh copy of Zen Cart and does indeed have custom modifications which aren't working for you.
I'm afraid that if you require any further help with this I'd need FTP and admin details for the site to take a quick look.
Hope that information helps though.
Enjoy the rest of your weekend!
All the best...
Conor
