When exporting my collection the size of the file was doubled and every time I’m running it either in the runner or in Newman the requests are running twice.  
Why is that?

Hi @assafsagee 👋. Welcome back to the Postman Community :postman:.

How are you measuring the file size before and after export? When you run the collection, does the entire collection run twice, or does each request run twice? It will be helpful if you can share some screenshots or additional info that helps us understand the issue better.
