Shipping: Shipping Zones and Rates are not working

[daisylegacyshop]

Hello, 

I am new to Shopify and am having trouble setting up shipping for inventory that I have on hand. I have tried to set up zones in North America using carrier app and rates. I also added a fixed rate. 

To make sure that this worked before making my store go live, I went to my store and tried to follow a customer experience (shopping, adding things to cart and checking out). I have no problem getting the items from drop shippers to ship to my address, but when I try to order things that I have on hand (personal inventory) Shopify doesn't let me check out because I "haven't set up a zone that delivers to me" ( I am using my United States address, so if I set up shipping zones for the US, it should let me ship to me. 

I have watched every tutorial on this, I have added all the weights to the items I have and also double checked to make sure that I am creating shipping zones that ship from my address. I have also selected packages and a default package style. 

Is there something that I am missing that I am doing wrong?

Same here, I have 3 different rate options, two work properly, one doesn't. And the shopify support doesn't get it either. 
So if anyone knows the solution, I would be gratefull to hear about it!
