little problem with path of product

-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.6.4

Hello
I have a little problem with the display of path of the product, just with 2 item menu
PLease follow this link and click on one product in the list:
dominio/aghi-principale/aghi-cartuccia
dominio/redskull.it/macchinette/bobina

You can see in the first case in the path I have:
Home / Aghi / Aghi cartuccia Crystal / Round Liner
in the second I have:
Home / Categories listing / Raffaello Titanio

All my links work as the first one so I prefer that format, but I dont understand why that happens for the second link.
What can I do??

Thanks
Frank

Hello
I solved deleting the path that I found in canonical url field in the products.
Why IN these product the field was filled??
I copied the path that i found in the canonical url in 5 products:
/hikashop-menu-for-categories-listing/product/raffaello-titanio
/hikashop-menu-for-categories-listing/product/prestige-ergal-titanio
/hikashop-menu-for-categories-listing/product/evo-rotary-black-opaca
/hikashop-menu-for-categories-listing/product/evo-rotary-red-opaca
/hikashop-menu-for-categories-listing/product/evo-rotary-purple-opaca

There is a reason for that??
Thanks

SO so sorry nicolas but I dont understand what you mean...

HOwever yes I have that setting in my configuration and maybe I understand why It produced that kind of wrong url.
I noted that if I create a new product and i forget to specific the category or if I forget to delete the general category and I assign the specific category too, when I save the product it generate the url following the path of general category.
Do you think that was my problem?

Thanks

I am little bit confused about how canonical url are created
You sayd "but when someone displays a listing on your website with that product on it.", I am not sure, but I think it generates different Url in base of how is displayd the product.
Example After I save the product if I reach for first time the product from list product it genarate a kind of url but If i reach the product from an item menu it generate an other kind of product.
That is normal??

OK so If i want fill manually what is the correct path??
Example
category/category1/product

That is correct
Frank

OK it is clear now, just a question about your possible path for canonica url:
{menu-item-alias}/{sub-menu-item-alias}/{sub-sub-menu-item-alias}...etc.../{product-SEF-name}/{product-id-if-necessary-}{product-alias}

About {product-SEF-name} that is what I find in option SEF url where there is Category Name and Product Name....correct??
My site is in italian language, do you think for optimization SEO is better translate Category and product or it doesn't meter??

Thanks
