Currency by country issue when using product bundle plugins

I am having a problem with the Currency by Country issue in the premium version. I have tried several different plugins to create product bundles, including YITH Free and Premium, also the WooThemes Product Bundle. Whenever, I create a product bundle and set a price using the currency by country module, it disables the discount that would be applied to the individual products, so that the cart is a sum of the price I set and all the individual product prices. for example my complete bundle should be £120 but the cart has a total price of £260.

I need to make use of product bundles to be able to have the products in the bundle as separate line items, as I use the API to send details off and get back unlock codes from a server which need to be attached to each line item.

Please can you offer any thoughts or if you know of any product bundle plugins that are compatible.
