Warning: Edge is much shorter than the specified minimum element size.

I am trying to mesh a 3D integrated concrete masonry block. The geometry is somewhat complex but the idea is that it is a layered apparatus: brick, foam, brick. I am trying to measure the R-value of this ICMU, so every resistance is important. When I meshed this to begin with, everything worked. I have now added a small layer of material in between at the contact of two materials to account for contact resistance. When I do this, the front of the block meshes great, but the identical backside has errors at 15 different faces. The error warnings in the progress frame are:

Mesh error (ftet1): Failed to generate mesh for domain.
Mesh warning (ftet1): Edge is much shorter than the specified minimum element size.
Mesh warning (ftet1): Face is (or has a narrow region that is) much smaller than the specified minimum element size.

All of the issues are at the filleted edges. Is there anyway to make the back mesh like the front. (The CAD part was imported from SolidWorks). I have attached screen shots displaying the front and back views of the part

Thanks!
