As I wrote up a document with lots of headings, on different levels divided by Heading 1, Heading 2 and Heading 3, I initially was bothered by how after each Heading 1 and Heading 2, which I always followed by Heading 2 and Heading 3 (respectively), it automatically started a Normal paragraph. But at least it also followed Heading 3 with Normal, as well, as I wanted.
However, as I continued, it eventually started following Heading 3 with another Heading 3! I'm guessing that on one occasion, I accidentally changed the Normal paragraph which followed a Heading 3 to Heading 3 itself, and Word took that as proof that I want to make series of Heading 3 lines/paragraphs with nothing Normal in between. It is not changing this new rule despite my correcting the style each time I press Enter.
How can I make Word give the right (most likely wanted) style each time I press Enter?
