On Enter Viewport, Multiple Timelines, Glitch

My document has colored sections and I’ve been asked to have each section load when it comes on screen. I was advised to use multiple timelines for this, which I did for the first few sections but it’s glitchy. When a section comes into the view port section, as I continue to scroll, it automatically restarts.

Im also confused that after I add a new timeline - each timeline, the new and the main show all the same layers. If I make a new timeline for ‘orange’ for example… do I delete the orange from the main timeline? I would think so…

If anyone could shed light it would be helpful. Thanks!
