How do I troubleshoot and fix OneNote section merge issues? Here are some things to try:

1. Open the OneNote section in two different windows.
2. Check to make sure that the versions in both windows are the same.
3. Try copying and pasting the page into a new location in the notebook.
4. Delete the sections and then re-add them.
5. Rename the sections to ensure they are unique.
6. Where possible, manually review the changes before merging.
