Shopping cart shows only the last 10 items of 20-30 added

I am experiencing the problem with shopping cart

My customers are complaining that while shopping they can’t see the full list of items added. Only 10 are visible and others just disappearing, they are still in cart but you can’t see them until you delete the newest ones.

Product is actually in the cast but not displaying neither on the phone or desktop. I used all different browsers and happens the same thing.

I think this is one of reasons why I have so many abandoned shopping carts, cuz people can’t see the product

Please help!

I am loosing my customers, please someone help!
