Menu Cart hover off page

When you hover on the Cart / Basket in the top menu, the drop down is off the page to the right:

The Cart is built on WooCommerce, the site on WP.

Although is doesn’t have this problem on the actual Shop page, only all the other pages.

The classes seem to be:

class “shopping-btn menu-item-has-children cart_wrapper”
class “shop-icon”
class “fa fa-shopping-bag”

Any ideas where I should be looking to problem solve this?

Or any tips on fixes?

Any ideas on this please?

Otherwise I’ll just hide it from all pages where it doesn’t work.
