How to turn off notes app formatting (numbered list)

In the notes app (iOS 10) I have some old numbered lists (no special formatting) and when I modify the numbered list now, it auto formats it and indents the number.

For example, I will type "1. First thing on my list" and as soon as I type the period after the 1 and hit space, it auto indents and formats it as a numbered list.

Maybe I'm just OCD but this is annoying, and all of my other lists are formatted in the old way (which I prefer). How can I stop the notes app from doing this?
