why does the color pallet shift in the texture property manager page?

Has anyone else noticed that in SWX2015, when editing the color of a model/assembly, as soon as you pick a color the entire pallet shifts to the right one square, resulting in a constant double-click to get the color desired?  Am I the only one having this problem?  This is driving me nuts!

This is what it looks like before the cllick (note the outlined color)

As soon as I click the desired color, the shift happens
