Post Title Slug Not Generating

I just finished a 17000 post Drupal to WordPress conversion.

Now, I have one problem. If you go to https://www.beststuff.com/ and to the second most recent post, whether you click or hover, it readers the main domain’s URL instead of a URL containing the slug ( /%postname%/ ) format.

Now, if I individually go in and update, the slug will generate… like in the 1st most recent post. However… is there a way to push through MySQL a way to re-generate without manually updating every single one of those 17000+ posts???
