Navbar symbol sometimes appears differently on preview

My Navbar symbol sometimes looks differently when viewing the website in preview.
For example, it appears correctly on my Home, Lookbook, and Contact pages.
But it looks different in my Shop and Blog. It shows up as a different color, and when I start scrolling, it turns white.

Does anyone know why this is happening?

I bought this template by Udesly from the marketplace, expecting to be able to quickly build a website. Everything is a lot more complicated than I anticipated, and I almost wish I had just built it from scratch so I know where certain things came from. I can’t figure out if there’s some sort of override that I keep overlooking. Would also appreciate any tips and suggestions to streamline this process while working with the template.

Huge thanks in advance!!!
