Minimum clearances in PCB stuck at 0.020

Yes,

I just found that here:

Clearance of copper pours

Hey all, I’m new to coplanar waveguide pcb layouts, and to do this I am using KiCad. I want to make this RF circuit to have 5 mil clearance around all the traces, and I’m laying down fresh (no netlist pulled in from a schematic). Whenever I try to fill a copper zone surrounding a trace, I never get a spacing (clearance) between the copper plane and the trace. Instead it looks like the copper plane is engulfing the trace. Any advice? I am trying to use a .005" clearance Thanks for your time…

Try this:

Double-click your copper zone. Copper Zone Properties dialog should appear.
Type 0.005 into the Clearance field.
Click the OK button.
Re-run the DRC tool.

Now the question is how I set it in the first place … its been a LONG day.
