PROBLEM Simple Contact Plugin - Language Problem

[SoHo22]

Hi there,
I have a multilanguage page (I18N) DE/EN/RU with the simple contact plugin. the form is translated in the three languages.

When I cklick on "Kontakt" on the home page the form on the contact page shows up not in german but in english.

Settings:
Language: de_DE
Sprache für alle Seiten mit einer URL ohne Sprachkürzel (wie "index"), z.B. "de":    DE
Language for all pages with URL without language abbr.: DE

Versions:
GetSimple 3.3.8
Simple Contact Form Plugin: 1.3.0
I18N Plugins: 3.3.1

Has anyone an idea how to solve this problem?


Thank you
SoHo
