Fix The Editing Music Bug – Coub Review

I enjoy using Coub a lot to make some short videos and all but there’s an error in the video editing I’m afraid. When I try to edit a music to where I want a song played and move the scale to wherever I want, it stopped short and lagged out. I did the 10 second music edit which I could frankly move my scale favorably but it didn’t fix the Manuel Scale. Can you please take a look at this type of bug and fix it back to normal?
