Do NOT go creating a new user profile based on what you've read. I don not know that it was necessary in the other thread and certainly do not know it is in your thread.
Another thing to try would be renaming your list gallery with Word closed.
Code:
C:\Users\%Username%\AppData\Roaming\Microsoft\Word\ListGal.dat
If no one else has done so by then, I will look at your document tomorrow. Now it is my bedtime.
