ZDoom

I recently acquired Ultimate Doom, Doom 2, and Final Doom through steam and I wanted to play it with mods. But every time I open the GZDoom, It always opens ultimate Doom. I know it should let me choose which version I want to play but it doesn't. I have already tried to copy the entire folder into the GZDoom folder but it always opens Ultimate Doom. I would like to know if there is something I can do

Try bringing down the console (~ key) and typing

hit enter then quit and restart.
