horizontal line in photoshop

I hope someone can help.  I have a Stock image that I used the magic wand on.  When I add it to my file it leaves a horizontal line across the rest of my images where the original frame of the image was.  I have tried deleting it and re-installing.  I have closed Photoshop thinking maybe it was a glitch.  Still there.

I know it is associated with the Stock image because when I hide the layer it goes away.  I am not a power user of Photoshop and would be grateful for any help.
