Isolated thermal dissipation zone?

Hi. So I’m running into a problem with something that’s supposed to be simple.
I’m sure I’m just missing something obvious.

So I have a ProFET that dissipates its heat through pins 5-8 (SOIC8) and what I’d usually do is slap down a fill (in altium) and it’d automatically isolate that fill from the polygon(Zone) and I’m sorted.

I made a Zone in Kicad to do the same thing, but it merges it with the ground pour…

What am I doing wrong?

I tried Googling… But I can’t get my keywords right.

kicad zones priorities

Or read directly at the documentation:
https://docs.kicad.org/ → PCB-Editor → section “working with zones”

Thanks!! Zone priority was the setting I was looking for.
