Page Table to Contents issue on Refresh (when ToC in its own container)

[jasonjac2]

Problem to Solve

I put my page ToC's in a separate container so they don't mess about with the Author stamps on the rest of the page. It looks like this:

I use these settings:

ISSUE:
When I hit refresh I get:

but not everytime.

This example I gave here was doing it, then it stopped, then I deleted the container and did it again and it started again.

To Reproduce

New Page
Add title
Add a few headings and text
Click on an unused bit of the screen and type ToC to get a new container
bring up ToC dialogue (I used CommandPallette | Table of contents).
1st time you get what you expect
Click refresh.
You get the issue

Environment (if applicable)

Version 6.4.0 with OneNote 16.0.17628.20144 - 64bit

Work Around

Just delete the ToC and recreate it.

Add any other context about the problem here. Attach page XML file or the app log file as appropriate. You can find the log file here: %localappdata%\temp\OneMore.log

THE FINE PRINT This is a hobby project that I started for myself. I'm happy to take requests and will promise to
consider each one carefully but offer no guarantees that I will ultimately agree to their
usefulness or have time to implement any of them. If OneNote offers a "close enough" work-around
then I will probably reject the request - you've been warned!
