No 2D Symbols Mechanical Systems

I'm having problems with 2D symbols not showing up on any file when I use the drawing extraction manager to create a duct layout plan in Bentley Mechanical Systems V8i. This 2D symbology usually shows when a duct is going up or down, or if a diffuser/grille is supply or return, etc....This occurs with or without HVAC Rules defined for the drawing definition. This also occurs when I run off our network standards and even when I run off the local bentley mechanical system install. Attached is a screen shot showing some ducts and at each end the 2D symbols are missing that should be showing the left side going up and the right side going down (All Levels are On). Help would greatly be appreciated. Also attached is the forward view settings for the drawing definition.
