Import fails with NumberFormatException

Hi,

we try to export through the Webinterface from one server and import it on another server but always hit this error message:

Der Import ist fehlgeschlagen. Grund: For input string: "nu"  ---------> The Import has failed. Cause: For input string: "nu"

I then tried the js-input.bat with the following results:

Role ROLE_PCT already exists, skipping.
Role ROLE_PROJEKTMANAGER already exists, skipping.
Role ROLE_ZB_QSHE already exists, skipping.
Role ROLE_ARNSBERG_REKLA already exists, skipping.

I already looked at the decompressed zip file but can't find the reason on this, i even removed the 2 latest users from the export but the issue still occurs.

Both Servers are:
