Yoast SEO problems with og:image, twitter:image

Hello! I’m using Yoast SEO plugin v4.2.1 on a new website, and although I have input a specific Facebook image in the Social tab, the source code grabs two different images, apparently from my website posts. I’m puzzled about why Yoast SEO is (1) posting 2 og:image files and (2) they are both the wrong files.

Based on reading on this forum, I’ve already tried: disabling my theme (Avada) and replacing it with WP’s default theme, and disabling / removing other plugins that might be conflicting. As long as Yoast SEO plugin is active, the og:image problem persists. The descriptions seem to be fine.

In the Yoast SEO plugin settings, this is what I have:

Social – Yoast SEO
Facebook
Add Open Graph meta data: enabled
Image URL: http://madbirdfilm.com/wp-content/uploads/2017/02/madbirdfilm-siteicon-1.png

Social – Yoast SEO
Twitter
Add Twitter card meta data: enabled
The default card type to use: summary

I’ll paste some of the pertinent source code below.

<meta name=”twitter:image” content=”http://madbirdfilm.com/wp-content/uploads/2017/02/filmfest_award_cinematography.png&#8221; /> <– WRONG IMAGE

Any ideas about what to do? Thanks!
