Estimate delivery not working in product page

Hi !

I created a design for simple products, there I added estimate delivery, everything works great but.

For the estimate delivery to be visible in the product page, a product (any product) has to be added in to cart, after that, I refresh the page and the estimate delivery is visible.

Is this the default/expected behavior ? If not, could you please guide me to where/what I should check ?

I tried to uninstall all plugins, move from sub-theme to main theme and this is still happening.

Best regards !
