Force Full Content not Working

I am requiring that each post has images so I select “Force Full Content” but then the posts are not showing because I also require that “Posts must have a featured image” but the plugin is not working to add the images to the post. I have been trying to figure this out for weeks but nothing is working. It used to work so I’m not sure what is going on. I also submitted a ticket last week but haven’t heard back from anyone. Here is one of the source URLs that is not working: https://www.google.com/alerts/feeds/09216257353125456863/6536263174852446679 . I see the new posts in the Feed Preview but none are importing because the force full content is not working to add the images to the posts.
