Language prompt in OSD phase after first boot

Hello @ all,

following situation:

SCCM 2012 R2 CU3
Windows 7 Embedded Sp1 x64
5 additional Language Packs 


when I deploy an captured Image (LPs included) to a VM, after the first boot into OS, I will be prompted to choose the language.
After selecting the language, the Task Sequence continues. I´m using an unattended file to select the language.

snip start:

snip end:

Any ideas?

Thanks a lot!
