A Issue with Zones from Surfaces

I think I'm not understanding something about creating zones from surfaces. Aside from labeling my surfaces with duplicate names, I have errors at intersections. There are roughly 15 of these type of errors:

When I made my surfaces, I created a separate surface at each intersection. For example, Wall A intersects Wall B and I created Wall C which represents the intersection of the zone. Wall C was assigned as its own surface in the assemblage of zones.

1. The simulation has not run correctly because of this severe error:
   ** Severe  ** GetSurfaceData: Potential "OtherZoneSurface" is not matched correctly:

2. The simulation has not run correctly because of this severe error:
   ** Severe  ** GetSurfaceData: Construction AIR WALL of interzone surface DH_EAST_2/3 does not have the same number of layers as the construction EXTERIOR FLOOR of adjacent surface DH_FLOOR

3. The simulation has not run correctly because of this severe error:
   ** Severe  ** GetSurfaceData: Adjacent Surface not found: DH_FLOOR_SRFP_0 adjacent to surface DH_EAST_2/3_DUP_DUP_SRFP_0
