Change URLs

Hi, great plugin!
I have a question …
I use the German language version and the urls to the glossary looks like this: http://…/Wörterverzeichnis/term
how can I change the “Wörterverzeichnis” in “lexikon”?

I’ve tried to change the language files with Poedit, but then the shortcodes didnt work right and on the mainpage of the glossary all entrys are shown as an archive page.. (like other categorie pages from the blog)

Anyway – thanks for this great plugin 🙂
