Illustrator Transparency and Masks Question

I have a circle with a black stroke and a rectangle with a black stroke that I'm using as a mask.

Using the Transparency tab I've been able to mostly get what I'm looking for with those two slices where they intersect to be cut out, but why is there that slight gray where I want it to be completely zero'd out?

Everything is at Opacity 100%. Is this a bug? Is there something about the Transparency tab that I'm just not understanding? I was hoping to still have the rectangle be movable so I can change the size or location of the part that is masked, otherwise I'd simply using Pathfinder. Any advice?

And it looks like the document came from a CMYK preset and was converted during or after creation to CMYK.

From the metada: <illustrator:StartupProfile>Print</illustrator:StartupProfile>

That should normally work.

Can you share that example? You can attach it here on a post when you save or rename the file as .pdf

Thanks, as Monika suggested, the RGB values have to be 0.

The swatch has been named black, but it isn't.

Is this an RGB file?

Then you have to make sure that those rectangles are 000

Also: does this get better in CPU preview mode?

It is RGB.
The strokes on the rectangle and circle are pure black.
CPU vs GPU unfortunately doesn't change it either.
