Pointwise to OpenFOAM: how to handle internal face

Actually I am working on the pointwise official tutorial case 'BackStep'. I export the polyMesh folder and use checkMesh to examine the mesh. I got the following message:
Checking topology... Boundary definition OK. ***Total number of faces on empty patches is not divisible by the number of cells in the mesh. Hence this mesh is not 1D or 2D. Cell to face addressing OK. Point usage OK. Upper triangular ordering OK. Face vertices OK. Number of regions: 1 (OK). Checking patch topology for multiply connected surfaces...

Face area magnitudes OK. Min volume = 5.4e-07. Max volume = 4.0563e-06. Total volume = 0.0162. Cell volumes OK. Mesh non-orthogonality Max: 0 average: 0 Non-orthogonality check OK. Face pyramids OK. Max skewness = 4.62963e-09 OK. Coupled point location match (average 0) OK. Mesh OK.
I think the problem is the internal face between the two blocks. OpenFOAM has problems with internal face, do you have any idea on this issue?
