short description of tables for MVKE & MARA are not in English

Recently we went to Upgrade to ECC 6.0.

I logged into SAP in English .

The short description of tables for MVKE & MARA are not in English when I log in using language EN. MVKE is Verkaufsdaten zum Material(in German language) instead of Sales Data for Material.

MARA is Allgemeine Materialdaten(in German language) instead of General Material Data.

I noticed this in MM17 and then did an F4 search in SE16 and confirmed the short text descriptions there are the same.

Could you please suggest me . THANKS IN ADVANCE.
