Has anyone had this issue where the bottom lift post comes up before the middle one? When cranking up, the bottom post on one corner will raise up before the middle one. When the bottom post gets to the top that's as far as the roof will go up. I can wiggle the bottom post and get it to drop down, sometimes it's easy, sometimes it takes me 30 minutes to find the right spot so it will drop down. Here's a picture of the lift post part way up- You can see the bottom post is up and the top post is floating inside it as the middle post is not in place. Here is the opposite corner where the posts are all coming up like they should- The bottom post is still recessed in the box. How do you get to where the posts are in the box? I'm guessing it's tear off the wall? Any help is much appreciated, Thanks!
