C# eInvalidInput SetPlotConfigurationName new PC3

[snappyjazz]

Hello,
I have code to print, but it doesn't print quite right. So I created a new PC3 file to use for my print. However now I'm getting an error at the PlotSetValidator.SetPlotConfiguration line. It's a runtime error "DB.WriteLine(" (See top screenshot).

Without an certainty I think this might be because the media dropdown is greyed out when using this pc3 to print (See 2nd screeshot). The SetPlotConfiguration command is trying to specify media where it can't.

Is there a way to print with custom pc3 files where the media can't be changed?
