opencart. iE. Why does the product in the cart appear only after the update?

Question

opencart

Hello!
Link to the site: www.littlebuddy.ru
Engine: Opencart 1.5.5.1
Browser: IE 10 I
describe the glitch:
1. We send the product to the basket
2. We go to the basket, the product is in place
3. We send another product
4. We go in, only the first product is displayed .
We refresh the page, the second one appears.
In other browsers everything works fine, it does not work only in IE.
Interested in any thoughts on this matter, even if you do not know how to solve

Answer 1

Caching? =)

Answer 2

if it is normal in other browsers, then apparently the reason is in js
