Navigation menu and its targeting


I got a Sticky nav, and trying to link each Nav menus(white dots) to the Sections.
Here is my website:

read-only link:

The problem is, when I click Nav menu, it doesn’t move right at the linked Section.
For example, the first dot is supposed to link the “program” section, but if you hit the dot, you go to the “Concept” section. So as the other sections.

I cant figure out what is wrong, so it will be appreciated if you help me out.

Thank you.
