I'm facing an issue in Magento 2.2.0 and Unero Theme 1.3.2 where there are products that have an URL like:

https://example.com/catalog/product/view/id/440/s/product-url-key/57/

and the others are:

https://example.com/product-url-key.html

I'm checking the condition of SEO setting in the catalog's configuration, but I think it's already correct in the store view level setting.

And this is the SEO settings in the catalog -> product itself

I'm currently at the beginning state of developing and learn Magento Programming. Do it need code modification in core / theme? Or there are something wrong with the configuration?

Expected result are the second one where there is .html in the product's URL
