why some elements can't be printed as pen color table set

hello all, 

I need some help figuring out what is going wrong on printing. 

I'm using OpenRoads Designer Connect Edition, ver 10.08.01.33

I need to print everything in monochrome (contour lines in grayscale) except for the background aerial photos. I did what I used to do: creating a pen color table and makeing all pen to be printed as black but the contour lines printed with grayscale. This time, for some reasons some of the elements, including part of the alignment, which is 3D model, and some annotation cells in the Sheet views, can't be printed as monochrome. 

I even edited printer driver configuration on the color maps part. Still, those elements are persistent to be in color. 

In the part of screenshot below, all colors are set to be printed as black in the pen color table and printer driver configuration. The station number is the in the model and the red bore hole annotation is in the sheet view.

Please help me to figure out what I missed.

Thanks
