Sorry for my bad English!

Anyone can help??

Abou the yellow boxes, could you take a screenshot of what is happening? I didn't understand.
About the 3D models, I don't have knowledge to help you. Sorry.

How do I fix this??

Oh, I got it now.
This happens because there are other files inside the Template folder that have these details (yellow contour and BVG symbol).
Inside your Repaints folder, open the .rpc file related to this bus on Notepad and get the name of the other textures the template uses, besides those two you've used. If I remember well, there is a file with ends with _AD and other one with _MU where there are this yellow boxes and the BVG symbol (on the _MU file, the repaint is kinda grayscale). Open these bmp files, remove these yellow contours and BVG and create the repaint again. Well, check all the files that are included inside the .rpc file and edit them to prevent these boxes and the BVG logo from appearing on your repaint.

Unfortunatelly I'm not at home right now, so I can't explain you accurately. But try to do this.
Please tell me if you could do it.

_MA = mask

and exactly what to do? Explain please!
