Duplicate Checkout on Checkout page on Elessi Theme

I am having a problem with the woocommerce on my payment page and I have the Elsssi theme running on my site https://www.guidaflex.it/

View payment fields, coupon fields and subtotal twice.
So far I have tried:

I uninstalled the useless plugins and going for exclusion I still have problems.

Any kind of help would be really appreciated or if there was some type of CSS that could solve it quickly for me I have a theme fix. Thank you!
