Why the incorrect update of the small basket?

Question

1C-Bitrix

Hello. I had the following problem: under the administrator's account, when I put the goods in the basket, 8 more third-party ones are added, but when I update, go to another page and go to the basket, everything is displayed correctly. I also noticed that if you do not update and do not go anywhere, but put another product in the basket on the same page, 8 third-party products are no longer added, but the basket is correctly formed (though with 8 extra products). Other authorized users and unauthorized users do not have this glitch. How can I fix it?
