Double pageviews - Invisible pageview trigger?

Hi
I have a quite strange problem.
I am not using tag manager to track pageview at the moment, I´m quite sure of this, but i get double page views for all users.

So i did a small test. I created a new website for a test environment.
In this test enviroment I also get double pageviews for all users. Checking the tag manager i see that there was a tag and trigger generated that contains a pageview trigger. When I pause this tag, I get normal results with only one pageview.

In the original site I don´t see this autogenerated tag but its like its there but not visible (i dont have any pageview triggers at all). Anybody that encountered a similar problem and perhaps has a solution?
