Sticky app component doesn’t stick

[Garry_Valette]

Hello Figmers,
Scroll behavior doesn’t work as I want.

What I want :

1. A fixed top bar as you can in attached screenshots
2. When I scroll, I want that my date component stay sticky underneath the top bar
3. Then the next date component below push and replace when I scroll down

Problem : Date component don’t stay stick underneath the top bar, it goes up to top edge screen. Moreover, date component below doesn’t push and replace.

Any idea?
