Translating Penumbra - model problem

[VoYtHAs]

Hey,
We have already translated Penumbra Overture into polish language, but there is a one problem.
In game there is an arrow with cutted off characters. Could you 'fix' this model? By fixing I mean to make it more simply - fill those characters with polygons .
In other words - make it like all other arrows in game.

Here goes a picture:


As you can see on there is texture with polish text but model is in english .

Thanks in advance - voythas.
