Detail Level: Not displaying correctly

[MRTArchitects]

Hello,

I am currently having problem with my detail level. I have a plan view which has the detail level set to fine, however is showing walls with a solid in fill panel. 

I have checked the phases and the visibility settings and 'by my eye' they look ok. 

What could be the problem and most of all what is the solution?  

Any help would be appreciated.

Did you look at the wall material being used for the walls and make sure it doesn't have a solid hatch applied to it for Cut Pattern?

That would be my guess if you checked V/G and Phases.
