White vertical spacing mobile

Hello,
I am fairly new to this and when I look at my site in mobile I got enormous white spacing between every section. It looks like the spacing of my first section effects all the other sections which I don’t want. But can figure how to change that. Can anyone please help me?

Here is my site Read-Only link.
