Description of the problem

As shown in the attachments, I'm using 3 black circles inside each other: The outer 2 circles have borders with no fill, and the inner-most circle is filled. I select the shapes using the Similar Color Selection tool, delete the shapes and replace them with Shaped gradient with black and white colors.

The result is that I get the shaped gradient, as well as what appears to be 4 square edges that appear in the outer-most circle (See attachment shaped_gradient_problem.png).


STEPS TO REPRODUCE
1. Create 3 circles as shown in the attachment
2. Select all the shapes together
3. Apply the gradient tool with the shape set to "Shaped"

OBSERVED RESULT

Square, solid colored edges appear on the outer-most circle

EXPECTED RESULT

The shaped gradient not containing the square edges (See the bottom of the attached image , which was created by applying the gradient on each of the circles separately).
