Unable to align isometric walls

I am having a hard time aligning up my tiles with larger wall tiles. For some reason the start of the wall is no where near the actual placed area of the tile. The Wall ends typically in the center of placement. I can provide pictures if need be.

Tiles: w64 x h36 (32+4 depth)
Walls: w64 x h224

I think one or more pictures would certainly help to understand your problem.
