Ghost Image In Site Origin Slider (Includes Premium No.)

When I place a sliders on a page the pictures appear but there is a second version of the same picture behind the original picture? It leaves a “shadow” of part of the picture behind the picture.

The graphic is in the background position with nothing in the foreground position.

I am using the theme: Tesseract

Your assistance is greatly appreciated.
