Languages missing in SM30 translation

Hi

After a unicode-conversion of our SAP R/3 4.7 we are only able to translate to English and German in trx SM30.

Example: Try SM30 on V_TVRO (Routes), and click "Display". Then select one of the entries ang choose "Goto-->translation" in the menu. Now a popup shows possible languages. Before unicode-conversion, app 30 languages were in the popup. Now the popup only shows English and German. Has anyone had similar experiances ?
