That's REALLY weird. Just tried it and you are right.
I did several tests now.
Enter event title and at least one character in the notes, then either click somewhere outside the new event to save it or as you described being in the title field and pressing enter, either way works.
The important point here is, that you MUST enter something in the notes, then it works.
I did another test and created a new entry with only title, which does not get synced. I reopened this event and added now something in the notes and saved that event again. That does not work, so you really MUST enter something in the notes when you first create that event, before it gets saved for the first time.
Anybody else able to reproduce?
