When I am creating a sales order for a customer who defaults to a certain price list, I choose some of our composite items to add to the sales order. The price from the selected price list comes up automatically. I then need to box these items by clicking on the little blue "box items" button. After I box the required number of items, the price changes by itself. The price reverts to the default price list. This means the price is now wrong, and I have to manually correct it. 

This happens for all except one of my composite items. 

Can you please fix this so that the price of an item does not change after I box these items?

Thanks,

Lizzy
