Dont "run as a Flask project"

Im working on a project together with a class mate and I can't get our project to not behaive like a Flask project. My class mate can run our files as a basic python files.

I have tried to create new projects a few times and pull from our repo but I cant get it to work.
Tried on two computers and also reinstalled Pycharm. Every time I want to run the file it wants to be run as 'Flask(app.py)' I dont know what is wrong. 

Any tips? :)
