Dents in mesh with addLayers

I am using openfoam 2.2.x for creating mesh using snappy tool.

When attempting to create layers around a square part which is located inside a duct, I see some dents / missing elements in the mesh along the edges of the duct.

The dents are seen only when addLayers is used as there are not dents after the snapping step (i.e., the mesh in '2' folder has no dents but mesh in '3' folder has dents - see attached pictures).

Any ideas ? Please help. Thanks.
