Issues with Customer Shipping Rates by Product

I've searched but I can't find this issue on the forums....

Shopify is miscalculating my shipping rates when I combine a product-specific rate with a general item rate in my store.  I've tried a few ways to trick Shopify into correctly calculating the rate, but nothing is working so far. 

First, here is the free custom rate for the product...

Here are my scenarios...

1). I offer free shipping for decals on my store, so I created a custom Free shipping rate.  When the cart contains only Decals, the free rate appears and any other rates I add for that item (priority, express, etc.).  When I add a flag to the cart, with only free shipping as the custom product rate, I get a shipping rate that's not event defined 

-Shipping $x.xx (see below)

2. If I add the standard carrier rates to the custom shipping rate for the product (decals), shopify is doubling the standard carrier rate.  i.e.

I want shopify to give free shipping for just the decals, but when any other product is added, I want the standard carrier rates to take over.  Right now, the only option customers get with combined carts is this standard shipping rate (which I guess is a backup rate).


How can I get shopify to correctly calculate the carrier shipping rate when a general item and an item with a custom shipping rate are combined into the cart?

Have you tried using the weight parameters for the cart, so decals are light weight so once the cart reaches a max weight is goes to the different rates?

Should allow you to have multiple decals in cart before it hits the limit. Just a thought.
