Mastery Page – Incorrect Font Colour

I was sorting out my mastery pages and noticed something peculiar. I know it's small, but it is still probably unintentional. A quick few searches on reddit, google, and this board showed no similar report, so if another one exists, my bad.

Notice how when you hover over Offense masteries, the mastery name has a red font to show it belongs to the Offense tree. If you hover over Defense, it should have a blue font colour, similarly Utility should have a green font colour. It seems that the font colours for Utility and Defense are swapped – Defense has a green font colour, and Utility has a blue font colour.
