Updating shipping options have some specials rules due to it being a custom module. I’ve listed the text below from the module’s README file for further reading.

Updating shipping methods require the following steps.

Uninstall Table Rate Shipping Module (in Admin)

=> open up the admin at www.domain.com/badminton/
=> select Modules => select Shipping
=> select Shipping Table Rate
=> select Enable Table Method : False
=> select Update
=> select Shipping Table Rate
=> select Remove

Update Shipping Options (on Server) *

=> open includes/languages/english/modules/shipping/table.php
=> add/reorder MODULE_SHIPPING_TABLE_TEXT_METHOD_*
=> save file

Reinstall Table Rate Shipping Module (in Admin)

=> open up the admin at www.domain.com/badminton/
=> select Modules
=> select Shipping
=> select Shipping Table Rate
=> select Install
=> select Edit
=> re-add shipping values (infinity:#.##)
=> select Update

You’re updated list of shipping options are now completed.

Feel free to read more below to understand more about the somewhat labor intensive method for updating/adding/removing shipping options.
