Batch mode /addsource sourcelang:"eng" adds files as "enu" (English) instead of British English

Hi all,

my batch command adds the files to my Passolo project but with the wrong language:

pslcmd.exe <path to lpu> /addsource sourcefolder:<source folder> subfolders sourcelang:"eng"

The files get language English 9 0 enu.

Is this a bug or am I doing something wrong?

Thanks, Markus
