520381 Oscommerce shipping 2

My Current shipping modules are basically 2 day shipping, 3 day shipping etc modules that have been modified. One of my rates is showing for some customers and not for others - this is a table rate. I have attached an image of the problem module. I want all my modules to be standard and I want options to add and remove them quickly with affect the fact that my category 'bulk loads' has been written to charge a delivery charge per item ordered - this must not change
