Orca Some lacks in translation to German

[hermann <steppenwolf2 onlinehome de>]

Hi,
where can I correct a lack in translation of Orca to German?
When I press the space key, i hear the word "space", but pronounced in
German, which sounds a bit silly. But when I move the cursor over a
space, for example in this text, i hear the correct German word,
"leerzeichen". Is there a way to correct this? In /orca/po/de.po there
is the correct translation, however it isn't invoked all the time (see
my explanation).
Do I have to add something?
Regards
Hermann
