NO BUG: Glitch/Repeat when added video background in nestable slider

Thank you, i tried with uploading two slide with same video and duration, still there is a glitch/repeat in the beginning of new slide. The video duration was 3 seconds and Interval in ms 3000.

There are few similar posts on error like this, but i am not sure, if anyone of these would work, i tried importing the code and placing it in the footer, but no difference.
