Home page using different template on live site than in editor

My home page seems to be using a different template than I see in the editor. In the editor, when I go to pages -> home page -> edit -> template, I can see it’s using the Front Page template which is one I created. It should look like all the other pages with black text for the header and navigation bar and white behind it. In the editor, this is what I see. However, in the live site and when I preview the site, it looks different. It has the picture behind it, white text, and a white line through the middle. There seems to be some other home template on top of it. When I inspect the page and look at the css, I can see the part that specifies the white font:

.home .header-area .wp-block-site-title a, .home .header-area .wp-block-navigation-link a {color: #fff;}

but there’s no way for me to remove that.

Can you help me to fix this?
