DevidS on "[Plugin: WordPress SEO by Yoast] Wrong url under Seo title"

Hi Joost,

I´ve started using your plugin with WooCommerce and I´ve found that some urls of my products under the seo title is wrong. For example:

The correct url of a product is:
https://myweb.com/shop/blue-shoes/

and under the title appears like this:

https://myweb.com/shop/blue-shoes-2/

Initially I´ve used an image for the product with this name but I've changed it and on the web it appear correctly but here the url is not right.
How can I do to change this?

thanks
