Padding issue

I believe this is related to the following code you have:

.vc_custom_1536959341732{
   padding-top: 30px !important;
   padding-bottom: 30px !important;
   background-color: #092942 !important;
}

Using !important on an element that is made sticky will disrupt how the plugin works, so if anything, please remove that from your code and see if that makes a difference.

I have removed padding but same problem.
still section cut out.

check please.

I see what you mean now.

This is because the target is indeed scrolling to the top of the screen, but since there is a sticky menu, parts of it will be hidden.

I’d suggest to add some top padding to your section titles (you’ll need to do that in Visual Composer), that way they will be visible and not obscured by the menu.
