Core Module Export/Import – Error

[ngrmm]

I tried to import pages from another pw-installation
The process results in an error as soon as it starts doing the import. All steps before ok (choosing destination, linking fields, …) working fine.
PW creates one page, sets the page name but is not able to set the page title and gives this error:

Schwerwiegender Fehler: Uncaught Error: Call to a member function setLanguageValue() on null in wire/modules/LanguageSupport/FieldtypeTextLanguage.module:159

Both sites have the same languages installed (default/de)

This is an example of my json:

Have you installed all the Multi-Language FieldTypes on both sites?
