Thank you for your input. I have a lot of experience with Photoshop, but I am a new user for this program. I have checked all of my wall connections and can find no problems. Under the framing view I have found a difference between the part of the plan that is functioning normally: see the right side of the shot compared to the malfunctioning portion on the left) . The abnormal section is missing floor headers. and ceiling joists. I am not sure how this happened, but looking for a fix other than starting completely over. any suggestions greatly appreciated.
