Can't modify/refresh facebook share popup box

I added a custom title, description and image using Yoast SEO for one of our recent post. When I click on the facebook share icon, the popup dialog box is not showing the custom info but just an url of the site. I used facebook debugger to refresh or release the facebook cache. The preview displayed the correct updated title, description and image. But, clicking on the facebook icon, the popup dialog box is still only showing our website’s url. Not sure what else to try to resolve this.

Here’s the blog that we are trying to get the custom sharing info to appear.
