Hi,
1. it's transparent because the original texture is replaced with the text texture (texID_draw). the solution is a second face in the exact same position (just copy the first one) which keeps the original material. the original needs to be placed above the one with the text in the list on the right side.
2. you probably can't see any text here, because the orientation and vertical orientation are both set to center. the text is written in the center of the texture which seems to be outside of your mapping.
