Blogger Template With Materialize Grid's Problem

Bismillah. Through this article, I want to share my problem with the grids of Materialize CSS in Blogger Template. Repeatedly, it showed me a blank columns every time the articles are not published in the same date.

I have asked to a friend, in a Blogger Help Forum, also in Stack Overflow, but I still didn't get any solution yet. It didn't mean that nobody answer my question, but unfortunately when I asked to Blogger Help Forum, an expert explained to me that Blogger Help Forum can not support custom setup from the third party template addons/feature, then it would be better to ask directly to Materialize Community itself.

He also said that the display of Blogger posts on indexed pages, is grouped by the dates the posts is published (on some default Blogger templates). Commonly, Blogger templates adds a surrounding

to group published posts by date. Then, probably I need an additional CSS, or try to remove the "added" div tag in the template HTML.

Kindly take a look this picture below to understad the problem more :

Can you help me solve this problem?
