v6 trial. Trying to fillet the inner edge of this using blend option (0.1 or 0.08) and it seems generate a surface across the hole!

The “surface” is actually a render (display) mesh problem, not a NURBS surface. Very strange.
Hello - I see this - it seems to be the existing fillet at the outer edge that goes wonky - still digging…
You can fix it by ExtractSrf
on that outer/top fillet surface and UntrimBorder
