The 'Select Variable to Insert' dialog currently lists variables that are not available to be used in the current context.
For example, when updating an Alert based on 'Player Location', Node and other variable types are displayed, even if 'Player Location' is selected in the 'Show Variables for' list.
The 'Show Variables for' should limit the variables for the context of the current Alert - ie. only show 'Player Location' variables for a 'Player Location' Alert when that option is selected.
