Graphic on multiple overdub!

is this normal this graphic on the waverform if you overdub more than 2 overlay?
You can see like a volume boost on track 2 , but only on the begin

This is a common graphical error, it happens sometimes, but is not reflecting the volume it is only a visual glitch.

We may fix this once we get to more polishing which may come sooner than later, I will tag it as #under-investigation

Thanks for reporting
