So,
door_1_obj is in the TextEntry parameter of your level door?
Things that mess me up sometimes is forgetting to hit save in Notepad++, or not hitting the Enter key after changing the value of an object's parameter in the level editor. Also, using the camelCaseConvention when naming things helps with readability, instead of using the underscore_between_words.
If you see your map's description when you select your CS from within Amnesia, then we at least know the file itself is located in the right spot and it's not accidentally set up like extra_english.lang.txt, which may happen by accident.
