Format a paragraph to new section

Question

I'm sorry if my question title is not clear, because I don't which technique to be called in my situation.

I have a layout like below image. In 1.2 I have 1.3.1 1.3.2 and 1.3.3

But in my document, I have 1.3.4 as below image:

So my question is: How can I make this section appear in the list, same level with others such as 1.3.2 1.3.3 ...

Answer 1

this works for me:

1. highlight entire line 1.3.3 (or any other line that works correctly)
2. click format paintbrush
3. apply the format to the entire line 1.3.4 (by left-clicking in its margin)
