You could also try to clean up yourself by cutting away the 3D corners.
Then do some cleaning where bend radii should be. As if it would be done on a straight press brake.
That means outside radius is inside radius + sheet metal material thickness. AND both radii should be concentric.
It could look like this:
Still not fully OK to my liking, but to give an impression where all this could get you:
I hope this gets you on a way.
