I have found that when I enable the header and description (Settings > Layout > Toolbar > General) that the default blog header and description show on the main blog frontpage as well as on every individual blog post view. This is, of course, redundant. To me it makes sense to show the main blog header and description on the blog landing page (frontpage) but not on the individual blog post view.
I found a reference to this issue already but it dates back to 2014. I'm wondering if the issue has since been addressed and I'm not finding the right settings? Or is the workaround described in the previous post the recommended action?
