Missing hidden lines in Creo 2.0 drawing

Hello Everyone, I am having an issue with hidden lines in the drawing as it is displayed on the monitor.   When I make each view "hidden" the hidden lines are the same color and pattern as the rest of the geometry.   however when i print or export to pdf or dwg it does show the hidden dashed lines.  I have been searching the forums and trying to tweak the pen table but no luck yet.   Any ideas to fix?

Here is my current pen table

! Pen 1 = white entities (object lines)

! Pen 2 = yellow entities (text, dimensions, cross hatching)

! Pen 3 = gray entities (hidden lines)

! Pen 4 = red entities (Highlight - Primary (Dark Red)Selected (Red)Secondary Selected (Orange) All items plot as solid lines:

! Spline surface grid (does not plot in drawings)

! Pen 5 = green entities (sheetmetal)

! Pen 6 = cyan entities (section)

! Pen 7 = dark gray entities (dimmed e.g. tangent edges)

! Pen 8 = blue entities (spline surface grid) [use for drawing perimeter border in format]
