Displays all product variations on the site.

Hello. I installed Drupal CommerceBox. However, when adding a product, I encountered a problem. In Drupal Commerce, when I created a product, for example, a t-shirt with different sizes, it shows only 1 product—the t-shirt—where you can select the size. But in CommerceBox, when you create a t-shirt also with different sizes, it displays not 1 product but as many t-shirts as there are sizes. As a result, for instance, if there is 1 t-shirt with 4 sizes, it shows all 4 t-shirts with the same name but different sizes, even though these products are in 1 group. How can I make it show only 1 variation of the product instead of all variations?

Thank you.
