Margins issue on Word

Hi there,

I am putting together a book on Word but the margins are causing me a real problem. I have done my margins and all of the pages seem to be fine, apart from the Contents Page where the numbers are. They seem to be closer to the edge of the page than the rest of the pages which are all perfectly in line. I have attached a few photos to point out better what I mean. I have checked the margin numbers and they are all the same measurements. As you compare image 1 and 2, you can see the gap between the edge of the page. The bullet point feature is not included for the numbers either. Any help would be greatly appreciated. Thank you so much.
