Twin lens reverse macro

I have started with some macro shots. And right now I'm reverse my Canon 50mm 1.4. But I also know about the twin lens reverse. You're putting one lens the right way, and the second lens in reverse on the lens connected the right way.

But when I do, I get seriously vignetting. I get this circle in the middle of image.

Any idea why I get this or how to remove it?

When reverse only the 50mm I don't get the circle.
