eShop : Clear cart, refresh and delete button don't work

Hello,I have a problem with eShop version 4.0.2.
When calling up the contents of the shopping cart, the update and clean buttons appear but do not work. Deleting a line from an item doesn't work either.
However, the two buttons below, continue shopping and order, do work.
Do you have any idea what's wrong? Bootstrap CSS and JQuery are enabled in the options.After adding a product, all actions (refresh, clear, continue, checkout) are working with the popup.
Thanks in advance for your help,
