Customizing header background color, text color, and link colors

Hello, I hope someone can help me. I am new to Beaver Builder. I may have a setting wrong or something, but I am trying to set up my website, and when I change the background color or text colors within the customizer, it does not update on the site. It changes in the customer panel, but nothing happens on the page. I have made sure it wasn’t asking for any updates and that everything was active, but I am at a loss now with why I cannot change things within the heading or footer in regards to colors.
