WPML posted the following suggestion:
Unser Compatibility-Team kontaktiert Plugin-Author..
..und könnten genauere Tips geben welche Code-Änderungen das Plugin voll “WPML kompatibel” machen. Oder es könnte etwas in unserem “Buddypress-Multilingual” Plugin hinzugefügt werden. Sehr gute Lösung, dauert aber oft einige Wochen.

What is the best solution for you? Make your Plugin full compatible with WPML or that WPML add some extra codes to their plugin “Buddypress-Multilingual”?
at this time I get a feedback, why the Widget-Title won’t get translated.
The Plugin is missing an “apply_filters” in the Widget-Title:
WPML will do some tests and get a feedback to me, right soon.
attached you will find a screenshot of the String Translation, where I can set the translations. But I don’t know if this will help you :-).
I wrote the issue also direct to the WPML-Support. When I have an answer, I will write it to you here.
