Help with installing custom content

[Captain Riz]

so I'm trying to install some mods (stories?)

Abduction
Tetris
One Light in the Darkness
The Labyrinth
To Give is to Force

(don't know if they're on here)

I've done it the way I understand it. I extracted the folders from the .zips and put them in the custom_story folder in the Amnesia folder under Steam. Open up the launcher, all I see is "Remember" and "Justine" along the bottom, dlc that came from Steam.

so I tried to put the folders in a different location since I have an amnesia folder under program files as well, made a custom_story folder in the redist folder and put the folders in that. same result. am I missing something really obvious?
