Composite product with product add-on

Hi, I am currently using your composite plugin along with the YITH product add-on plugin. However I have noticed that the extra amount that should be charged when customers choose the desired ”add ons” doesn’t add to the final amount when the price on the composite main product is set to nothing and the setting to include or excklude base pricing. In other words it only works properly when I have assigned a base price, but this way it’s impossible to have different pricing based on which composites that are chosen. Do you have a solution for this or a recommended plugin?
