@brandingbytonik - Check to see if you have the file totals.php within your theme folder/woocommerce/cart/ folder.
If you do, open it up and search for the class name "cart_totals". Let me know if you find it. This is probably the cause of your issue. Because if I add the class to your form, it starts working.
And it seems this is ONLY affecting your cart page, not your checkout page. So cart page is the one that is not working and checkout page does work.
Not too sure why it would show the shipping again on checkout page though.
