Full page JS on one section

Hello friends! I’m trying to get a full page scroll to work on the first section only and to have the rest as a normal scroll. An example is here: https://codepen.io/alvarotrigo/pen/BKjRYm

In the documentation it says " To create smaller sections just use the class fp-auto-height in the section you want to apply it. It will then take the height defined by your section/slide content." I did that but still no result.

I did follow everything but for some reason, it’s not working. Can someone help me with this please, what do you think?
