table.php override does not get picked up by Admin

Hi,
I copied this file
/includes/languages/english/modules/shipping/table.php

to

/includes/languages/english/modules/shipping/my_template/table.php

the file contains
define('MODULE_SHIPPING_TABLE_TEXT_TITLE', 'Table Rate');
define('MODULE_SHIPPING_TABLE_TEXT_DESCRIPTION', 'Table Rate');
define('MODULE_SHIPPING_TABLE_TEXT_WAY', 'Best Way');

Changed text in the override table.php file shows up in the shop checkout-shipping options as expected but the changes of _TITLE and _DESCRIPTION are ignored in the admin-modules-shipping section.
Admin continues to pick up these two strings from the original file, not the ones in the override directory.

So any extra table modules have to go in the original directory to allow their descriptions to be seen in Admin.
Otherwise it shows
MODULE_SHIPPING_TABLE2_TEXT_TITLE instead of what you have called it.

This does not seem in keeping with the upgrade/override mantra or have I missed something?

regards
Steve

The Admin does not have overrides at this time.

OK thanks,

I understood that the Admin files cannot themselves be overridden, but this is a case of a legitimate override file being ignored by Admin which I though was a different scenario,

thanks
Steve

Files in /includes/ do not apply to admin. The /admin/includes/ files handle things for the admin side.
