Cannot Create Sub-categories Under Category With Same Name

-- HikaShop version -- : 3.1.1
-- Joomla version -- : 3.75

Under "Product Category" I have:
- Women
> Clothing
> Shoes
> Etc...

and I am trying to create:
- Men
> Clothing
> Shoes
> Etc...

But it's giving me the error below when I try to create the sub categories under "Men". I need to create the same subcategories for both Women and men as I've done before in previous versions.

Error
An element with the same alias already exists
Error Saving

Thanks!

Hello,

In HikaShop, for products and categories you can't duplicate aliases.
So your two categories, even if they have the same name must have different aliases.

Regards,

Oh I see. The alias was the issue.

Thanks!
