JabRef version 5.0-beta on Windows 10

Thanks for the new beta build!
The new beta build has a few, uncritical, quirks I want you to inform of.

In the German translation of JabRef are a few cases where the word is preceded by an ampersand (&).
This is the case in the following menues:
Datei -> Importieren -> Importieren in aktuelle &Bibliothek
Datei -> Importieren -> &Importieren in neue Bibliothek
Werkzeuge -> &XMP-Metadaten in PDFs schreiben
Werkzeuge -> &Einträge in extern Anwendung einfügen
Werkzeuge -> &Abkürzung der Zeitschriftentitel aufheben

EDIT:
Hope a quick update of the translation files fixes the issue. See translated file.
