Category assignment bug

Bug when assigning categories. Using the copy functionality in the "list products" section, after assigning a category to a product, the category is written in its card. When you search for this product using the filter by category, there are no products in this section of the product. There is also no product in the selected category on the site. The product is searched on the site only by the article, there are no such positions in the list of products by category. It was revealed that this happens when copying a category using the copy-paste functionality and the built-in copy-paste pop-up menu. If you select a category by the input method, the category is assigned. Also, if you select categories using the mass functionality in the products list section -> assign category, the categories are assigned correctly. Now, due to this bug, more than 30,000 products are located somewhere. [file]198[/file] [file]199[/file] [file]200[/file]
