Power Clip bug?

I power clipped this shape (With a the red and white stripes power clipped in that shape) into the Right sleeve and it did this. Its clipped in the torso and neck pieces as well but only the sleeve shows it externally. The left sleeve is exactly the same and Ive copied that over and flipped it and it still does the same thing. Ive seen this a few times in the past but this is by far the worst Ive experienced this.

How can I fix this?
