V14: What is the difference between connector notes and connector notes?

[bknoth2]

The title is not a typo.

1) Open a sequence diagram
2) Right click a connector that designates a message. Select properties
3) A "Connector Properties" dialog opens which has two tabs at the bottom ("Connector Properties" and "Connector Notes")
4) If you don't see a "Notes" window at the bottom of the "Connector Properties" tab, drag the bottom of the dialog down to expand the view and review the (stealth) notes field below the "control flow type" box

Now there is a "Notes" box visible on the properties tab and there is an entire notes box on the "Connector Notes" tab. What is the difference? I know they are different because notes typed into the window on the properties tab show up on the diagram if sequence notes are visible but "connector notes" don't.

Given that, at least on my system, the "Connector Properties" opens in a way that hides the notes window at the bottom (see step 4) above) it took me an hour over two days to figure out why my notes don't show up on the diagram (which I was typing in through the "Connector Notes" tab) but notes entered through V13.5 do. To make it worse, notes entered through V13.5 seem to show up in both notes fields (the one on the notes tab and the one revealed by step 4) above) but notes entered through V14's "Connector Notes" tab don't show up on the diagram but those entered through the properties tab do.
