Issues with Carving detail

Had an odd issue with an Easel Pro carve last night.

I was working on this easel project

The main stem of the leaf thing on the right hand side just would not carve. In the end i had to tell easel it was a 1/32 bit and then it carved it. Looking at the simulation and the detailed preview it looks like it should carve but it just skimmed the surface and didn’t carve down at all. I tried increasing the depth of cut but still it avoided it.

Any ideas?
