No Add Button on Settings > Focus Page

I’m trying to follow the instructions for creating a new Focus on my iPhone 13 Pro Max (running iOS 17.0 (Developer Beta (21A5326a))).

I do not see an Add button (blue +) in the upper right side of the page that lists my current Focus options. I have a total of ten options set up and I want to add another.

Here is a screenshot of what I see:
