Duplicated post

First, I am not so good at English, I searched the forum before this topic, but I did not get any idea to solve my problem.

I have several (for example two) categories, three post list (latest post, category-1,category-2) and 4 posts(post-1 & post-1 under category-1, post-3 & post-4 under category-2).

I use the Multiple Loops to display my posts in my homepage, and use “$do_not_duplicate” to avoid duplicated post.

Now the problem is, when latest post lists Post-4, post-3 does not display under category-2.

See https://golfreader.cn

Is there any suggestions if I want to show post-3 while post-4 is shown in the latest post list?

Thank you very much!
