Andre, your formatting for the chapter heading is a bit difficult to figure out.

You want to have your Heading 1 on two right-justified lines and are trying to have each line have its own formatting while being under the same style. When I look at "CAPITULO 2", you have a first line indentation of 4.8" (you possibly see it in centimeters), and in the custom multi-level list, you have Heading 1 (Capitulo) followed by an automatic tab character.

You might want to try replacing the tab character in the multilevel list settings with "nothing." Then you can manually insert a line break (shift + Enter, not just Enter for a paragraph break) between Capitulo 1 and Introdução. If you want a double space between Capitulo 1 and Introducao, but not a double space between Introducao and the line, an easy manual way of doing that is turning off the auto spacing and adding an extra line return there. I tried updating your table of contents (incide geral), and it brings both of those on the same line there.
