Using Hikashop starter

The shop will be selling both physical and virtual goods. I'm trying to configure the "pay on delivery" plugin. It will be used to mark an item that it will be PICKED UP IN STORE, and PAID AT STORE. I'm testing with an item configured for a weight of < 1kg (where the shipping method has a certain cost for that weight class)

However currently when choosing pay on collect, the shop currently still ensists on adding a shipping cost. I then tried adding a "manual shipping" but it still adds "free shipping" next to "collect". I know i can add a language override for FREE_SHIPPING="", but what if at a certain point if the purchase amount goes above a certain number i would like to offer free shipping. Then the Free shipping method would have no "free shipping" next to it.
