Sorting does not work with FacetWP Plugin

I am using FacetWP plugin to create a product filter based on Product Categories and Product Types(variations).

Unfortunately this plugin is not returning products in desired ordering. If i disabled FacetWP plugin, I can see correct ordering.

I have checked and FacetWp is also returning products ordered by ‘menu_order’ in ascending Order. As per docs, Re-Arrange WooCommerce Products plugin also uses same ordering functionality but something strange is happening due to which I am not getting expected results.
