Hello
I have tried to change the data of the template customer-new.php
more exactly I have removed the Mr. selector and the fax field
I have added card number, selection of month and year of expiration and name of the owner. payments will be made at the hotel, but we want the card number for security.
It worked, but, that data does not appear in the reservation management panel. The mr and fax selector continues to appear.
Should I change something else in another template?
I do not program, I do everything by observing and copying.

In the link page are capture of screen.

The path in which the template was modified is: /app778951251/wp-content/plugins/wp-hotel-booking/templates/checkout/customer-new.php
Thank you
