shop and cart headers shrunk

Hi,
My Shop and Cart headers seems to have shrunk down such that they are overlapping into the details of items in cart and too near product listings in Shop. There is discrepancy as when I go into “customize” the live preview shows it exactly as it’s supposed to look (and as it did look just a day or so ago).

Here are my URLS:

Cart

https://fjarildesigns.me/shop/

I only seem to be able to attach one screenshot now~ I’ve attached the view of the correct looking cart, as it appears when I’m in “customize” for the cart page
