Editor seems be to ignoring the Player -> Scripting Define Symbols

So I have a script that adds build settings. If I look at the Player settings window I have the define I want, "KRELLWARE_TD_ON" set in the current build, iOS as an example. In the scripts, I have #if KRELLWARE_TD_ON statements. They are NOT active even though the value is set in the Player Settings iOS. I am not sure what I am missing. From what I have read the editor should include the Sciprting Defines Symbols for the currently selected build. But it does not seem to be working...
