This change ensures that the items numbered 5, 6 & 7 appear as individual paragraphs with a list number instead of being run together in a single paragraph. The change inserts an extra blank line between list items which ensures their correct formatting.
However, the last sentence of item 4 is now indented incorrectly (it currently has no indent) but it was getting too complicated to figure out how to get all the content of item 4 indented correctly while also fixing the remaining items so decided to split the tasks.
