Yes I had this problem and sadly I never found out what was causing it. To make long story short, within the same bookcase, I assembled the higher shelf which worked flawlessly without any problems. When trying to do the same thing with the lower shelf I ran into this problem. I was using exactly the same method as for the bookshelf above. No matter what I did, the problem didn't go away and after a whole day of fiddling with it to no avail, I eventually copied the entire upper set up and pasted it on the bottom.
I was asking the same question... why was it only happening to the lower bookshelf if both bookshelves were done by the same method?
