Navbar Scroll access to edit content unavailable

Hello there

I seem to be having a bit of difficulty accessing the Navbar scroll text on the text links to change the name. I bought a template. I have used Webflow before, but this template offers a Navbar scroll for when the header becomes out of focus. It’s a one page Sectioned site.
Problem is, in the design editor, although the Navbar Scroll is a symbol in the Navigator, and I can see the Navlinks, I can’t seem to visually see the navigation in designer to update the text so I am unable to change the text.

I was hoping someone could help me with this issue?

I hope this makes sense.

Here is my site Read-Only:

Hi all - just to let you know that I sorted this out after about 5 hours of trying!
If you are interested, I needed to remove the scrolling position to have access to the navlink names. Doh!
