I am having a flat rate shipping error.

I have it configured to charge 8.50 per unit, It seems to be working properly, but there is the orange/yellow indicator that tells me it isnt.

I have it set-up as follows:

Flat Rate

Enable Flat Shipping
True

Shipping Cost
8.50

Tax Class
Taxable Goods

Tax Basis
Billing

Shipping Zone
New York ( New York )

Sort Order
1

I'm thinking it has to do with the Shipping Zone or sort order. I never have been able to figure exactly what the sort order is.
