Thank you for your feedback. When the Unidoor Plus is installed correctly, your panels will line up perfectly at the top. It sounds as if your moving panel may have been installed too low. There should be a 5/8" space under the moving panel, which will make the panels line up perfectly at the top. We invite you to contact DreamLine Technical Support Team to discuss your installation. We can be reached at 866-731-2244 M-F 8am to 6pm. Or email us at support@dreamline.com.
