Description

Hi recently I have been using quarto to be able to write some academic papers, however in the university they ask me for some features such as:

Chapter I

1. INTRODUCTION
   1.1 Introduction
   1.2 Problem statement
   1.3 Objectives of the problem
   1.4 Importance and Scope of the Research
   1.5 Limitations of the research

So the index quarto I am using is as follows:

# CAPÍTULO I {.unnumbered}
{{< include capitulo_01.qmd >}}

# CAPÍTULO II {.unnumbered}
{{< include capitulo_02.qmd >}}

# CAPÍTULO III {.unnumbered}
{{< include capitulo_03.qmd >}}

# CAPÍTULO VI {.unnumbered}

Note that I am using an extension called nmfs-opensci-titlepages
Now my file capitulo01.qmd is configured as follows

# INTRODUCCIÓN 
## Introducción
### Planteamiento del problema
### Descripción de la problemática
### Formulación del problema
## Objetivos de la investigación
## Importancia y alcance de la investigación

Does anyone know how I can correct this structure? 🙏 😢
The version of quarto is 👇

You need to use keep-tex: true and investigate your latex file.
Once you've found the incriminating LaTeX code in that file, you can fix the issue in the template, partials, or in the titlepage extension.

• https://quarto.org/docs/journals/templates.html#latex-partials

I'am afraid there is no debugging shortcut.

Note that the layout is usually defined by the document class which is srcbook in your case.
So, I suggest to look on the Internet in more LaTeX specialised places to figure out how to tweak srcbook.
Overall, your question is unrelated to Quarto and is about LaTeX theming.
