[LANG] doors wont show text

[Dutton]

Speaking of Categorys. I'm quite confused about them. I don't really understand if every single category you type, has to be something special to work? for example the level doors. as you said:

"If it's a level door the category name has to be "Levels" and not "LevelDoors"
Like this:
<CATEGORY Name="Levels">
<Entry Name="Study_Door">Study</Entry>
<Entry Name="Storage_Door">Storage</Entry>
</CATEGORY>

How do you exactly know when it has to be a specific category name?
