The mostly likely reason why results in Table of Authorities don’t match your marked citations:
Hidden citation marks that you did not know were in the document.
Why are citation marks hidden?
When Show/Hide ¶ feature is turned off hidden text is not displayed. (Hidden Text is not printed, so you don’t see citation marks in a printout.)
Why would citation marks already be in a document?
Reason #1 – Re-Using an existing document that contains (hidden) citation marks (saving a copy of existing document.)
Reason #2 – Pasting text from another document that contains (hidden) citation marks. When you copy text – and Show/Hide ¶ feature is turned off – you would not see if citation marks are within the text you copy.
