When using the Generative Fill option, it places a border around image.

I am taking an image then increasing the canvas size.  Selecting the inverse of the original image and then using the Delete option with contents set as Content aware.  then using the generate option to generate the extended image into the increased canvas.

The problem is that when I finish the generate process, it places a rounded border around the original image.  

I attached my instructions that I created with all the steps and screenshots.  The last screenshot is the final product with the border that is not desired.

    Is it an actual border or a visible seam?

     

    Resolution Mismatch (1024 Limit): Generative Fill creates content at a maximum resolution of 1024x1024 pixels, regardless of the document size. If you are expanding a high-resolution image, this smaller AI-generated patch is stretched to fit, resulting in low-resolution, blurry edges that look like a border.

    Tight Seams in Generative Expand: When expanding a canvas (e.g., using Crop), the AI may not perfectly blend the edge of the original photo with the new content, leaving a visible line or "frame" effect.
