I have list chosen, not thumbnails. And each post has thumbnails anyway.
I want to delete the second related post and can’t find a way to do it.
You can exclude posts by tags or categories. So I’d add a tag to that 2nd post (eg “don’t recommend” or anything) and then excluded all posts using that tag. Eg https://i.imgur.com/vrYOFc4.png
What are those blue icons? Very strange
Those are the default thumbnails for posts that don’t have a featured image. It looks to me like you might want to instead use the lists display or add featured images to your posts.

Could you please send us some debugging info?
Here’s how:
1. From WordPress admin dashboard, under “Settings” click “YARPP”
2. Click “Help” in the top-right corner
3. Click “Optional Data Collection” tab on the left
4. Copy all the monospaced text

Hopefully, that will contain some clues about what’s going wrong.
