[Plugin: CGM Event Calendar] Language

I have some issues with languages and CGM Event Calendar. The .mo file (I checked it with “Codestyling Localization” Plugin) shows that the terms are properly entered and they seem to work for the rest of the site.

For example:

M_Monday_initial	m
Monday	mandag

or:

March	mars
Mar_March_abbreviation	mar

But the events in CGM Event Calendar are still in english, where do I have to change that?

Thanks for looking into it.
