Actually Janet the upper arm of the DeWalt saw is designed to not stay up on its own. This is an advantage for us top feeders. When feeding from the top, I lift the arm with my right hand wile aligning the blade to the next hole with my left hand. Then let gravity lower the upper arm and the blade into the hole. If this is what you would like to do, then yes, this is wrong. However if you are a bottom feeder, then it would be advantageous for the arm to stay up by itself.
