Issue with Configuring Keys in smart_moving_options.txt

[JDitz100]

Modifying the value of move.grab.default.key.name has no effect in-game. I have tried putting in several different keys (my objective being setting it to C), but the action remains stuck on LCONTROL. Not all options in the file are dysfunctional as I have successfully modified values in the flying section. I would like to note that the other 3 keybindings in this section appear in the game 'Controls...' menu but this one does not, and they do not synchronize the values in smart_moving_options.txt when modified in the game menu. If you could sort out this issue, it would be much appreciated.
