Given the bug with the formatting where it doesn't reset the subpoints (that's not the bug I'm writing about), I've noticed that when you get to the further roman numberal subpoints, when you have a longer roman numberal, it "beings" your line where you type after it still within the roman numeral.
The above screenshot is after I hit the spacebar a couple times. The below screenshot is not spacebar with some random letters typed after getting the roman numberal sub point automatically made by the note.
