Hi @Chuck_Braman, thanks for your post. I took a look and it does not appear that you are using Sections for linking but div blocks, there is a difference.
For section linking to work best, the sections should be placed directly under the body element in a natural document flow where Sections are placed under the body, divs are placed under sections. You can use anchor links to other elements using the ID, but the scrolling is more predictable when linking to sections under the body.
There are also other caveats to section linking and smooth scrolling in relation to Fixed nav menus: Getting Webflow's smooth scroll script to align correctly with fixed headers/navigation
When using fixed nav menus, the disable scroll offset in the menu should be checked and the first section after the nav menu (the top of your page, the first section) should be set as a header in the Type dropdown in element settings.
If you are using top or bottom margins between divs you are linking to, you made need to add the occasional margin offset somewhere, I actually recommend to use as little margin as possible, I try to never use margins but use padding instead so that all elements that are aligned vertically on the page in a normal dom layout have no vertical whitespace between elements.
p.s. you can tell if you are using a div block or section from element settings:
I hope this helps.
