When you click on the cart in the Search for a product block, adding the product to the order occurs only on the second attempt

Good afternoon! We have a problem with the Search for a product in the order block, when you click on the basket to add a product to the order, the product is not added, when you click again after a few seconds, two products are added at once, the problem is repeated in different offices by different managers on different devices I add a video, done already with a second click, that is, you can only see the addition of two products at once. Unfortunately, it is not possible to remove even the first click. Any ideas what might be affecting? Can you fix it?
