How to return disappeared products in Wordpress?

Question

WordPress

The store had goods. It was necessary to add variable and simple products. First, I uploaded the file and updated the existing ones, and marked only the product type field for updating to make the desired ones variable. Then I added new products from the same file. At first, there were fewer products in the admin panel, then they appeared again. Again updated the existing products from the same file, but this time all the fields. There are only two products left in the admin panel, after the word "All" in brackets there are several hundred of them. What is it connected with? How to return goods? The question is urgent.
