return air ducts

hello my question is in the return air duct ( 36 inchs wide ) I was cleaning them out and I had noticed that between the 2x4s when you look up there is a 2x4 only on one side to stop the air from coming in from the atic and on my other return in the master bedroom there are none should these be blocked off or not.thanks for your help steve f.
