Hello! First, thanks for you help!
The Bar Problem: I already had checked the “Hide initially” Option see --> 
The Trigger doesent work. Normally the sticky bar should come @ 20% after scrolling.
The Height Problem: There i got a few Problems. I gave my row a class named “Hero_Text_Row” and put the following code in the row css:
.Hero_Text_Row {
top: 50%;
transform: translateY(-50%);
left: 0;
}
Then i gave the Section “height:100vh;” on the inline CSS. On Desktop it all looks great, but when i look at my iPhone 7 in the Safari Browser, the Code doesen’t work and it does cut the complete row:

The Second Bar Problem: I fixed the Problem and changed the height in the second bar to auto.
