Cloning storepickup problem

I need to give my customers the option to pick up their order from two different locations. I thought cloning storepickup.php into storepickup_two.php would do the job.

I cloned it, globalreplaced storepickup to storepickup_two and to STOREPICKUP_TWO and altered the strings that display to the costomer (e.g. "Store Pickup Two" and "Store Pickup Two (Walk In):". I then istalled the new module from Admin.

The problem is that, while "Store Pickup Two" displays as a a shipping method at checkout and allows to be selected, "Store Pickup (Walk In):" is always shown at Step 3 of 3 - Order Confirmation. It should display the altered "Store Pickup Two (Walk In):" but it doesn't. To make sure it's not due to missing out on editing the cloned .php file I changed the original storepickup.php to display "Store Pickup 1(Walk In):". Again, when the storepickup_two.php option ("Store Pickup Two") was selected it displays the the original storepickup.php's motto "Store Pickup 1(Walk In):".

This happens with the store both ON/OFF Down for Maintenance.

Any ideas?

Thanks
