Blog Layout

Hi,

im using the grid layout with 3 columns on my blog page. In the side bar are the archive articles.

If i click on a sidebar article (for example October 2021) the blog articles have another layout. Not the grid.
Articles shown with a small thumbnail and a big header bar under the thumb. This doesn’t look not so nice.

Link for example: https://naturheilkunde-akademie.at/blog/

Can i change the results of the sidebar archives it in the same grid layout as my main blog page?

Thank you for helping!
