German translation

I have a question concerning the German translation of Event Calendar WD. It seems to me that there are several text strings, which are not translated and still appear in English.

I tested it on a local and on an online installation of WordPress and had the same problem both times. The missing translation are only on a few sites. I changed the language of my WP installation to see if it would affect the plugin. And it did indeed. The language changes on the “month”, “list”, “week” and “day” view. But on the “single” event page, on the organizer page and on the venue page, there are missing translations.

All those translations are missing:

event-page:
the ecwd_back_link: “View Calendar” (“Zurück zum Kalender”)
“Phone” (“Telefon”)
“Website” (“Webseite”)
“Address” (“Adresse”)

venue-page:
“Phone” (“Telefon”)
“Website” (“Webseite”)
the title “Upcoming events” (“Kommende Anlässe”)

organizer-pag:
“Phone” (“Telefon”)
“Website” (“Webseite”)
the title “Related upcoming events” (“ähnliche / zugehörige Anlässe”)

I am not too sure if this has something to do with my WordPress installations or if these translations are actually missing. I couldn’t find an easy fix in the language files either.

Is there any way to fix this?
