Filed holes in Cura

Hi! I've modelled this and don't understand why the program closes the two holes on the top.
I hope someone can help me.

Thank :)

That one will have to go back into the CAD app for repairs.  It looks like the breakage is a result of the fillet around the model and the embossing.

This is in Cura's X-ray view.  The large red areas are bad surfaces inside the model.  The embossed lettering appears to go 2/3 of the way through the model.

When I tried to fix this in MS3D Builder, a lot of the features simply disappeared.  That means it's back to the drawing board.
