The total price isn’t shown until I refresh

Hello,

This is my website: simply33food.com/en

The first 4 products on the website (the special offers) are built with PPOM addons, so whenever the users goes to add to cart, chooses any of the products and adds to cart, the price shows 0 in the pop-up cart. After the refresh the price is corrected, but it still has some bugs.

1. Go to the website
2. Click on add to cart – Order 2 quesadillas and get 1 as a gift
3. Choose 1 and 2 quesadillas
4. Add to cart
5. Check the price on the popped up menu
6. Refresh the page. Check the price – it’s fixed

How can I make the price right from the beginning?

Thanks
