How can I found out which module is causing this? Strange because there is no offline credit cart module on the 1.3h version of zen cart.

This 2nd "Credit Card" option option being displayed was never there before.
These are the only enabled modules:

ceon_manual_card - default
money order - default
PayPal - Processing
Paypal - Processing

When I remove every single module I am still left with this second off line credi card module add on.
Thanks for your help.
