Chart/Sonar Problem

I have a Dragonfly Pro7 which has developed an issue when using the chart/sonar option. The sonar portion is distorted. Sonar by itself is ok. Attached pictures show the issue before and after updating software. Two of the pictures are out of the water so the images reflect this, but you can still see the line on the right side of the sonar portion while the sonar only is ok. I updated software and reset sonar and still have the same issue. Suggestions?
