Share image isn’t showing

Most of my posts, the image shares great! however…there is one post I created the same day as another (and that turned out fine)…nothing different in creating the post…yet the image will NOT share that I set! Just my page logo I’ve tried changing the sizes (yet never had to do that with others) I have found since a couple of other posts that did not carry over the share image as well….not settings were changed, esp today when I created 3 posts. What could be the issue and where do I look for it? Is there a glitch somewhere??

The only difference is this has a single image within the post itself…but the set shared images are done the same
