Unable to change capitalization of names with new minecraft.net name changing systems

Recently, you guys have made it where you change your minecraft in-game-name through minecraft.net rather than through mojang.com. While I think this is for the better, I have noticed one bug. I am unable to change the capitalization of one of my alt's names(file attached). This is a bummer, since I like to switch from all lowercase to capitalized. This is obviously a bug(i hope) and it has probably already been reported, but I just wanted to put it out there anyways.
