Gray blurs still present in the contours.

What am I doing wrong? On light backgrounds the image looks good, but when placed on a dark background, white parts can be seen in some spots. Is this really the case, or am I doing something wrong?

Original image:

Start by reproducing the reported contour artifacts with the provided prompt, model, sampler, settings, and transparent-image mode, then inspect the generated image on a dark background. Done means the white or gray blur is no longer visible in the contours of transparent-image results.
