Disabling/Changing Shortcut Key of Screenshot Does Not Work

[Dax Solomon Umaming]

Disabling or changing the shortcut key of screenshot prompts gnome-control-center to create another key-value pair with the original setting. It's a Unity2D specific bug since I don't have this problem on Unity.

I'm attaching a screenshot that shows gnome-control-center with duplicate hotkeys for taking screenshots.
