Contest banner missing in some accepted entries Answered

I have two different contest entries that have been accepted and they show up on their respective contest pages, but the voting banner is not displaying inside the instructables.

This appears to be a sporadic issue since two other contest entries that were submitted around the same time in different contests have the voting banner displaying properly.
