Why does my disk utility look like this, and what should I do about it?

What specifically do you think needs attention?
That is normal for the current macOS APFS format.

Ah thank you. I had accidentally changed View from "show only volumes" to "show all devices" and wasn't familiar with how it looked. I was worried something had been formatted incorrectly.
