Hello, I'm trying to create a timeline that pins a sidebar when you get to the section on the page and updates the active image as you scroll through the years. It is partly working but seems to skip the first image altogether.
I've created a CodePen here:

It is based on this official demo:

Thanks for the great plugin. Any help is appreciated!
