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:
and the others are:
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
