World Editor duplicate GUI bug

The action “Set Variable” has a bug where the word “Set” appears twice in GUI.

Two examples:
Set VariableSet Arthas = Arthas 0032
Set VariableSet FormationRegionArray[8] = Formation 08

This makes triggers unnecessary bloated with the word “Set” and when you configure the action. Please fix so it appears like this instead:

Set Variable Arthas = Arthas 0032
Set Variable FormationRegionArray[8] = Formation 08
