Happiness Issue Under 1.8.497102

I just conquered a set of worlds owned by the Altarians and added a leader to one of them.  When I went into the planet management screen to look around I noticed that, while 3 of the 4 citizens had approval of only 6%, the icon was a green smiley face as shown below (the fourth citizen was a criminal so he didn't care  about crime being at 100%).

I think someone should take a look at the logic that determines the icon that appears in the lower right-hand corner of each citizens picture since, clearly, 6% approval should not get a green smiley face.
