"X" cross on images is a common issue with wide angle lenses and variable ND filters. Physics limit the capabilities of variable ND filters on wide angle lenses.
When you enter the edge of the max range,the "X" issue may appear on your image. Because you are using it beyond its capability according to the laws of optical physics,which will inevitably cause this phenomenon.
