1. How can I display extra tabs that I created with Woocommerce Tab Manager?

2. Please take a look these:

http://epicaccountstore.com/checkout-page/#1497965150440-b52a63a0-a36d (Built with theme)

and http://epicaccountstore.com/summoner-carts/ (default from the theme)

If you see the page built with the DT plugin and view the “Your cart items” section, you find that the “apply coupon” and the “update cart” buttons look really generic with no style applied at all. Now, move to the cart total section and you will find length of the table to awfully big and wide. Plus, no style has been applied to the “Proceed to checkout”. It should be in a blue box.

3.  Now, move down the page and view the cross sells section. As you can see, the theme is already applying some texts and border on the cross sell element I applied from your plugin.

I have more issues, but I need to fix these first. Please assist me in this. Thank you.
