Ads not showing on pages, blogs and feed pages , showing only in posts

I want to ask if you can offer some help, as the title is saying ads are not showing on pages, blogs and feed pages, they are showing only in the posts.

So, in the homepage, or the main blog feed page, and other important pages and all categories and tags feed pages there isn't any ads throughout the pages, ads are showing only in the posts.

Not sure what could be the problem, cant find recourse with this problem to read here so I wanted to ask what could be the fix.

Also have some troubles with the analytics, but let's try step by step I guess.
