The jungle door icon is different the actual door. When placed, the bottom half of the door should have a clear vertical window in the center. This window is shown in the inventory and hotbar and when the door is held in either of the players hands. The attached pictures show this little discrepancy.  I will admit that the picture named 2016-10-17 isn;t mine. I copied it from report #MC-108842, by user Harry Wright. I am using it to show said door while being held.
