Full zoom in 6700 waterfall rate scale wrong

This has been bugging me for a while.
I posted about it 2 months ago. Got no traction and was told that others need to chime in for it to be considered a valid issue.
This time around I decided to record a video.

This is on 40, listening to CW with the 6700 all the way zoomed in.
Look at the first yellow/green line/artifact on the waterfall. The video starts when that line is at the -2 second mark. The video ends when that same line is at -20 seconds, about 18 seconds later... funny thing is, the video length is 25 seconds. Where did the 7 seconds go?

When fully zoomed in the waterfall about 50% slower in the Flex 6700.

This might not be the case on the 6300 or 6500 which can not zoom in as much.
