Numbering in Word is notoriously tricky.

Try right-clicking on the list section that continues the 1. numbering instead of advancing to 2, and select "Restart numbering". It might do the trick. Or, it might not. Hidden section breaks can also cause problems, and sometimes one has to take the section out of the document, set it up in a black document with the same template attached, and then bring it back in.

Does that work?
