Header Not The Same On All Pages

My site seems to be not showing the correct page styles for some pages but correct for others. For example, https://kraftenterprise.com does not match same styling as Testimonials | Kraft Enterprise Systems. The navigation is completely different and sometimes there is two of them.

In the image below the top navigation is correct but you’ll see the bottom one looks incorrect and has two of them.

Your server side cache is too aggresive, example add cache busting args to both urls and they render fine.
https://kraftenterprise.com/?a=b
https://kraftenterprise.com/testimonials/?foo=bar

I imagine you made a change in the theme customizer so it has rebuilt its css, but your server has hard cached all the pages so the css is now a 404.

How would I go about fixing that then? I do see it correct from your link you provided.

You need to clear the cache on the server, some hosts add a plugin that adds a clear cache button in the wp dashboard, others have tools in their control panels.
