Layout feature not working

Hi,
we have a problem with layout feature for single product page. It worked just fine, and just stopped. It pushes the content to one column, on half of a page ( see attach ). We use the same theme and same builder ( WP bakery ) on couple different websites, and it works just fine. Do you have any common issue that you are aware of, related to this feature? Without layout, product page looks normal… When we try to use any layout, or try to create custom one, the product page content is pushed to the left column.

Any idea what causes this?
