Why isn't the side panel going to the case text even when I click on the case in the text?
This is because the field needs to be "activated".
To resolve the issue, simply click outside the field - the body of the text for example - and then click back on the field. If that fails, save and exit the Word document, and re-open it.
Note: Do not make changes to references directly in the body of the document. Any changes you make will revert when the reference refreshes.
