Why isn't my Fashion Express app showing up in shipping locations?

[Cibasti]

Hello,

We have installed the app Fashion Express and added a couple of products. 

Now we wanted to set Free shipping to the products but Fashion Express doesn't show up in the list of different locations. So I can't add them to General Profile or make a new one.

And Fashion Express really doesn't understand the problem. They continue to say "no need to setup shipping when it's free shipping". But yes I do.

I tried to manually add FashionExpress location in Locations and yes; then they show up so I can add them to my Shipping Profile but the checkout still says "This order can’t be shipped to the address you entered. Review your address to ensure that all fields have been entered correctly and try again."

Please help,

Paola
