Vantage-bb Theme – Blog page header not displaying page title

I have set up a new Header template and called it Blog. I added in a Text module instead of a Title module, and wrote in “Blog” as an H1 title. I saved this header template as a Regular template. I then went to the page I’ve set up in my site settings as the page to use as the default Blog archive page, and made sure that my new Blog header is assigned as the header template. However, this never displays on my Blog archive page. All I see is “Header – 1” as the title of the blog page. I’ve tried applying my Blog header template to a different static page and it displays fine. It’s only when I’ve marked a page as the default Posts page does the header display for some reason just pull the name of the header template, not the title of the page itself. Any insight into why this is happening would be appreciated.
