Hi @PRAYTHEPO , thanks for your report. We are working on improving this feature and mainly fixing the current issues we have…
But the behaviour you’re seeing is by current design I’m afraid. If you read description in Snap to zero parameter in Config (and as the name suggests), the marker will “snap to zero” when it’s close to a zero point. In this case (since Start marker is only 3ms away from beginning which I believe to be 0 point) this makes it close enough to “snap” to it. That is my assumption, but please share the project or describe further if you want us to analyse this more. Thanks for your contribution
