Why won't my object activate?

I'm currently trying to port a game I made along time ago in Unity to Android, and back when I created the game, I created a MobileSingleStickControl Object with a Joystick and Jump Button in case I wanted to port it later. Now I come back to the project, but I can not re-activate the Joystick and Jump Button, no matter how many times I click the check box.

The parent MobileSingleStickControl Object is activated, it's just the child objects. (The Joystick and Jump Button.)

Strangely, I can activate the Text, which is a child of the Jump Button.

Anybody know what's going on?
