Just an esthetical behavior, nothing to realy worry about.
In the pic attached I can't uncheck Move Left, unless i check one of the options from "Move the Mouse Cursor to a Location" and then return to check Move up only.
In "Adjust the Mouse Cursor Location" options, maybe it needs a way to uncheck an "option move" when it's not needed. for Example A checkbox to enable/disable the RadioButtons Left/right, and onther one for up/down.
