Well, it seems, you wanted to use the epic extension with the "Scenario Editor" module,
that´s wrong!!!!!
Use my game vassal module and my epic extension, so you don´t need 2 modules for setup scenarios AND playing

You simple setup the scenarios with my module, save the map(board) as picture, and save the setup. So you
can immediately use the setup also to playing on Vassal
Did you see this help guide?

and don´t unzip the downloaded files (sometimes computers do this automatic after download!)
If there are still questions, let me know
