Cart does not empty when administrator orders

-- url of the page with the problem -- : teszt2.honlapkeszitespecs.hu/
-- HikaShop version -- : 2.3.1

Hi!
I have a problem when I test the checkout as administrator.
I have set the empty cart when order is created.
I log in as administrator, I put something in my cart, I finish the process, but the cart shows that something is in there. When I click on the cart it says that it is empty. But I have to refresh the page twice after finishing the checkout process.
When I order as registered user it works fine.
What could be the problem?
Thanks!

Hi,

My first idea is : cache system.
Otherwise I see that you're not using the latest version of HikaShop, so maybe it's something we already fixed.

Hi!
