Misleading/False message given when exiting keybind controls screen

When exiting the options screen for changing keybinds by pressing "Done", and regardless of whether any changes are made to keybinds, the user is shown a warning message. It informs user that multiple actions are unbound.(seemingly without checking), and further alarms the user with "Are you sure you want to continue?" 

This message can only be avoided by using the "Esc" key.

After making one keybind change, I had to:

• Determine whether I had unintentionally overridden another keybind
• Hit escape to skip message to return to the options menu without pressing "OK" or "Done"
• Return to the keybinds screen to "Reset" all keybinds
• Become frustrated when pressing "Done" again shows the warning message.
• Repeat prior actions to verify the program logic is beyond confusing
• Make the single change I want to make to keybinds
• Ignore the warning message and click "OK"
• Return to the keybinds screen to ensure all other keybinds were retained

All this was necessary to change "Rotate" to the "Q" key because I missed my oldschool wireless Trackman.
