@Cassie i've tryed to minify code and leaved only one tween which has a problem. https://codepen.io/paketaaa/pen/wvmRjYL
I'll try to explain one more time.
When you scroll, you make left element active and translateY parent element to child element's height, but in my case when you scroll to the bottom and then back to top, parent's translateY not equal zero. I hope i explained well. I also want to tag @GreenSock because this man helped me last time with this case but with my changes it's not working like i wanted to. Thanks in advance for your reply.
