I18N <> p01-contact: Problem with interchange of GS´s Default-language

[TeeJay]

my page is running untill now single-language (multi-language as preparation - but the client doesn´t make a point of it). At that time (on 3.1.2), I didn´t found out easy ways and let the site run like this ...
But I just notice, that when I'm logged-in, in the backend, the p01-contact-frontend-labels switch to german, if logged-out, the frontend-labels switch back to english again ... ?
best, B.

What the... hell? Look at here:

Code:

http://yourwebpageaddress/admin/load.php?id=p01-contact_gs

You can set the language of the form there.

I have a web in Czech and English, GetSimple admin panel in Czech and also the p01-contact in Czech. Then everything is Czech.

But even when I change the webpage language to English, that is the problem. I want the p01-contact in English when I switch webpage language to English
