Hello,
I have an easy fix for you. 
My blog page is https://chiyucenter.com/blog.
If you go there, you’ll see that the first post shown is from August 2017.  Also, it is in the category “Classes”  which I have listed as a Category Exclusion for my blog according to your blog customization options.
I need my blog to show my newsfeed correctly — with the latest news first (not old news from August).  Also I need the category exclusion option to work.
Please fix and send out a theme update.  Looking forward to a fast fix.  Thank you!
Erika
