Enfold+WooCommerce need to keep a categories filter widget on sub cat pages

Hello guys

I have searched up and down for a solution to keep a widget placed on left side bar of woocommerce on all subcategories pages.
I set in Enfod -> Sidebar Settings -> Sidebar on Archive Pages -> Left sidebar
So at this point i have the left sidebar as wished on categories and subcategories pages of WooCommerce.
In that sidebar i added Product categories widget and configure it to show Only show children of the current category as i intend to use it like a filter only for subcategories. And till here it works fine.
The problem is when i reach the last subcategory the widget disappears because that subcategory does not have any child cat.
Is there a way to hard code somehow that widget to stay also when i open the last subcategory?
Because i need to keep the “Only show children of the current category” setting as i don’t want to see all the shop categories everywhere.

Now it shows till here:
/product-category/main-category/Leve1-subcategory/Level2-subcategory/

and i need to have exactly the same widget displayed till the last sub category

/product-category/main-category/Leve1-subcategory/Level2-subcategory/Level3-subcategory/

Basically to use it like a filter between level3 subcategories.

Thank you very much
