og:images are not showing on Facebook Posts

Hi,

We use WordPress SEO by Yoast at out site spotlight.usheru.com and we are having an issue where our og:images are not shown in Facebook Posts.

Facebook Open Graph Object Debugger is not reporting any error, and it can find the og:images properly.

For some posts it shows them in the og:image section, but not in the section “When shared, this is what will be included”. For example:

https://spotlight.usheru.com/monsters-never-see-want-see-coming/

Other posts the og:images are just shown blank, but when we click on them we can see the actual image. For example:

https://spotlight.usheru.com/makes-successful-hollywood-franchise/

Pleas advice.
Thansk a lot
Andres
