Okay, so I didn't know this went into a discussion forum. But, second, I came across the page on Creating Custom Styles (https://marked2app.com/help/Writing_Custom_CSS.html), and I'm taking a look at it now to see if perhaps having the CSS structured in a particular way will get things working.
Any style that I pick in the preferences. It doesn't apply. The default style is stuck. This was a fresh installation of the program. Maybe you have some kind of preference file from an old version that the new version didn't create or created incorrectly.

@john style looks fine. I'm going to have to recommend that you delete preferences and reboot to see if that solves the issue.
To delete your preferences with the MAS version of Marked 2:
Quit Marked 2
Delete the file at ~/Library/Containers/com.brettterpstra.marked2/Data/Library/Preferences/com.brettterpstra.marked2.plist (and any other files starting with com.brettterpstra.marked2). If you're not sure how to access this folder, open Finder and press ⌘⇧G, then paste "~/Library/Containers/com.brettterpstra.marked2/Data/Library/Preferences/" (without quotes) into the box.
Reboot the computer (this is important as macOS aggressively caches preferences and may just restore the deleted file without your knowledge.
Launch Marked 2
The directions for doing this with the direct version are the same, but the preference file is located in ~/Library/Preferences.
