Magento 1.9 Shipping Method is not visible on checkout page

I am having an online ecommerce store. I had used flat rate for all the products with same delivery charges. When I add the product on my cart, then my cart only shows main price of the product but not showing the Delivery charges. I had cleared all the caches & fixed indexes, but still facing this issue. Sort Order is “1”. I had attached an screenshot of frontend & backend for better understanding. Any help will be appreciated.
