Duct work question: Is this correct?

We just bought this house and I noticed that their is no airflow coming from the vents upstairs at all. I got to checking and I found that someone has installed a piece of sheet metal to block the airflow to the main trunk that feeds the upstairs vents. If I open it all the way there is plenty of airflow upstairs but hardly any downstairs. It's reversed if I push it in. I was just wondering if this is the best way to do this or if there is a better way? Here's some pictures.https://m.flickr.com/#/photos/138200...7/23374279411/

So in the winter.... there is no flow to upstairs based on the writing.... is that correct ?

Many times a damper is installed originally when the ductwok is installed and then you just adjust at the change of seasons. Same thing with that sliding damper. You don't have to slide it all the way.... adjust it for a happy medium.
