User blog:Super Sub-Zero/Alternate Colors not appearing, and some are locked?

Okay, so when I select an alternate color, it says colors 7, 8, 9 and sometimes 10 are locked. How do I unlock them? I tried looking it up, but I couldn't find anything.

Plus, when I select an alternate color, and I'm scrolling through the list, colors 14, 15, 16, 17 and 18 do not appear. For an example: I can be on Color 13, but when I press over, it skips me to Color 19.

I know there is some DLC, so maybe that's why some of the Colors aren't appearing, but what about the locked ones? Does anyone know how to unlock them?
