Blender import: Two faces refuse to show

I have a model which is a .blend file. When importing into Unity 4.6.1 two of the faces refuse to show up. I have checked all the normals are facing outwards, and also tested swapping them a few times.

Does anyone know what might cause that?

Check if you have "import" in normal option. Try to reimport your model or export to fbx. Check if there is the same faces number in Unity and Blender. You have to know if these faces exist or not. Check your modifiers.

Thanks, I did try your suggestions and could see that there were the same face numbers.

It turned out that the issue was with the way the face was modelled in blender. There were 2 very nearly overlapping vertices at two corners, but had not been fixed in a remove doubles sweep. This was causing two faces to be layered on top of eachother. Merging these vertices fixed it
