blog – Blogger shows 8 posts instead of 10 on the home page

I have a blog on the blogger platform (https://playstation1gr.blogspot.com/). On my home page, there are 8 posts while I have it set to show 10. This is how I have it configured.

I tried to put "jump in" in the last message in different points, but nothing changed. I also tried it in the ninth post, but nothing happens.
