[LANG] .lang file not working?!

[PutraenusAlivius]

Alright I've modified it to what I really need:

Here's a Screenshot of the Area that is supposed to work but doesn't since the extra_english.lang file doesn't seem to work.

And here's the code itself, while the key description + name and the area won't show:

<LANGUAGE>

<CATEGORY Name="Inventory">
<Entry Name="ItemName_key1">Private Study Key</Entry>
<Entry Name="ItemDesc_key1">Unlocks the door to the Private Study.</Entry>
</CATEGORY>

<CATEGORY Name="Signs">
<Entry Name="TestSign">This is for testing purpose</Entry>
</CATEGORY>

</LANGUAGE>

I think you need the description too in order to work....
