We do not have access to your Vendor Dashboard. In order to check and make sure you have setup your products correctly, please follow these steps:
1. Look up your products under whichever categories you listed them. Review your variables and descriptions. Instructions to setup variables are here: https://wedevs.com/docs/dokan/vendor-dashboard/products/
2. Add your products to the shopping cart.
3. Go through the shopping cart process until the payment step. If your shipping comes up correctly, then you are good to go.
4. If the shipping does not come up, then you need to read the shipping directions page, follow the steps and re-test.
