Blog List Not Updating

Here on Blogger, I find that one particular blog list of mine will not update. It all started when I posted an article to the wrong blog and tried to corrected it. I deleted the post and the blog list from that blog still says 2 weeks ago with the snippet. I even tried to make a separate blog list on the blog to see would it correct itself. Still, there was no change. I tried posting the blog list to another blog, and still there is no change. I do not know why that blog list will not update even after clearing my browser. It could be a bug that needs to be fix but I do not see why when the rest of the blog list is updating.
