this is something I've struggled with as well
yesterday's journal note displays as "9" in the hierarchy, despite the title being "09"
I haven't figured out why or how to control it yet
another odd behavior that I see is when the journal hierarchy is named "session" or "sessions" specifically
the new journal notes are titled with the entire date for some reason
for the moment, I'm just changing '2022-08-10' to '10' as journals are created
strange as it is, you could choose to adopt this format if you'd like
