Editing blog page issues

Hi,
One of my pages is called blogs.

When I go to this page in the space where I can edit it, the content is almost empty. However, when I click the button ‘view page’ in the right top corner, I get to see the page with all my blogs (instead of what I added in the page in the editing space)

When I am on the blogpage itself, I see in the topbar ‘edit POST‘ instead of ‘edit PAGE‘. When I click on this, edit post, it brings me to one of my blogposts instead of to the page of the blogs. So in short, I am not able to edit the blogs page somehow.

Where does the content in the blogpage come from (the raster with all my blogs)? Where can I edit it or add other things? How/where is the blogpost connected to the blogpage?

I have some (test) content in the blogpage but it is not shown on the blogpage.

For me it seems like a mystery.

Thank for the help in advance!
