2 URLs generated for each category when removing /product-category/ slug

Hi,

I’ve installed your plugin and used the option to remove the /product-category/ slug.

The problem is that both URLs are visible:
domain.com/product-category/category1
domain.com/category1

I’m using the free version.

Is your plugin supposed to work like this? Does the premium version redirect to the correct category URL?
(From: domain.com/product-category/category1
To: domain.com/category1)

A bit worried for SEO and duplicates.

Thanks for your time.
