No bug, that's what often happens when some numpty adds a post to the same pool more than once and doesn't fix it. Just remove the post from the pool and re-add it.

Edit: Or at least, if it is a bug, it's been around since forever and doesn't cause much of a problem.

Also such problems are more suited to a comment on the post in question than the forums, but that doesn't matter so much.
