Our Layouts are built for the theme itself and we have elements from the Theme that are fully compatible with the Layouts and theme. Those message shows when you use an element from Elementor Pro in our Layouts and those elements may not show the preview, but in the result, they work – https://prnt.sc/CVNlYieQcFi0
We have our own elements for the custom Shop, product, etc. pages so I suggest using them instead of elements from Elementor Pro.
