Known issue? I’m not the developer, but it’s news to me.
So I want to understand your setup, I want to look at it if I can find some time.
You have a static front (home) page and on this page you are showing the first 4 blog posts.
Then on the blog page you don’t want to show these 4 posts. How many blog posts are you showing per page on /blog/?
In the mean time, a simple solution could be to set the posts_per_page option to 5. Show the number of posts on the home page based on the posts_per_page setting and then link to page 2 of the blog and put a 301 redirect in place to redirect page 1 of the blog to the home page. Not the best solution, but it would have the same effect.
