Wauthor With EDGE (PLZ HELP)

I have made a cool level in Wauthor. (it uses no of the special Edge features) The map works fine with doom legacy. But when i run it in edge all the pedistals ive made turn invisible. (stairs to) Some areas dont exist and some walls are not there. The whole level is realy strange.

I am making a mod and i need Edges DDF script to make it. But i cant build levels in anything but Wauthor. Plz help me.
Could i maby run the map through some kind of tool that will make it compatible with edge?
Anything youst help!

If you see a .gwa file in the same directory where you have your wad delete it and try running the map through Edge again. This could help you out.
