Copy Coordinates keybinds reset upon restarting the game

Steps to Reproduce:

1. Change either key bind for Copy Coordinates or Copy Facing Coordinates
2. Close Minecraft
3. Reopen Minecraft

Expected Results:

-Set keybinds are remembered

Actual Results:

-The key bindings for both the Copy Coordinate settings get reset to their default values ('C' or 'X', plus Ctrl+Alt), even if the individual keys are already in use for other actions.

I've attached an example video where I change those keybindings, restart the game, and they are reset to their defaults.
