"posts" settings affecting home template

I’m trying to create a separate page for all blog posts while maintaining my static home page with the butterbelly layout.

Figured out I must go to Reading Settings, switch Front Page Display from “Your latest posts” to “A static page”, then choose the desired page as my “Posts Page”.

All good, EXCEPT it messes with the Butterbelly theme home page. My logo previously sat over a translucent white bar covering the top quarter of the home page image. When I change the settings as described above, the translucent bar disappears and my logo sits above the large home page image. What gives?

How can I keep the main page looking the same and also direct all blog posts to their own separate page??
