I've not tried rest on a 3d part quite like this before and I'm not sure how well it'll work. There are quite big steps from the previous op, not sure ignore cusps is meant for this amount of step. Also undercuts seem to confuse rest machining, from what I've seen in the past it's like the op sees the material in the undercut so generates a pass even though it can't cut in that area.

Also the rest is working to a certain degree as when set to stock model you this. Just a tip there's no need to enable stock contours and rest, stock contours are ignored when rest is enabled.
As opposed to this with rest from previous. Also think material left at the bottom height is being seen.

If you look at the first image it's clearing every level so with rest enabled it's only seeing material near to the surface of the model.
If you move the bottom plane up 0.1 and enable Ignore Cusps you get this. The red paths are ramps so not really machining, just getting to the area for machining. Ignoring the ramps there's hardly any cutting so rest is working but I think you're expecting too much on a curvy 3d part like this.

What are you expecting from the second pocket op after the first has remove most of the material just leaving steps? If you just want to clean up and remove the steps why not use a very course stepover parallel with the 12mm cutter. Something like this with a 5mm stepover, set slope to 0 - 89°.
I used a boundary set to tool outside.

I wanted to machine an area that the previous op didnt machine, but later i realized that i had a body there selected in the setup and that's why it didn't machine that area.
But no mater what, it shouldn't cut the air. I disabled stock contours as you said and set the rest machining to "machine cusps", and it cuts the air...
