Why does my header show Chapter 0?

Question

Why does the code below produce a first page with the header Chapter 0? I need to eliminate that.

A MWE which reproduces the error-

\documentclass[12pt,twoside
%,draft descomentando produce el pdf sin imágenes
]{report}
\usepackage[headheight=18pt,a4paper, width=150mm, top=25mm, bottom=25mm, bindingoffset=6mm, headsep=18pt]{geometry}
%aca utilizo la geometría de la hoja 
\usepackage[spanish,es-noquoting]{babel}
\usepackage[utf8]{inputenc} 
\usepackage[T1]{fontenc} 
\usepackage[hypcap=false]{caption}

\title{\vspace{-6.0cm}{\small A}\\~\\

    }

\usepackage[pagestyles]{titlesec}
\newpagestyle{mystyle}{%

\sethead[\small\itshape\thesection.\enspace\MakeUppercase{\sectiontitle}][][]{}{\small\itshape\MakeUppercase{\chaptername~\thechapter.\enspace \chaptertitle}}{}
\setfoot{}{\thepage}{}
}
\pagestyle{mystyle}

\begin{document}

\begin{center}
\maketitle
\end{center}

\titleformat{\chapter}[display]
{\normalfont\large\bfseries}{\chaptertitlename\ \thechapter}{0pt}{}
\titleformat{\section}
{\normalfont\Large\bfseries}{\thesection}{1em}{}
\titleformat{\subsection}
{\normalfont\large\bfseries}{\thesubsection}{1em}{}

\titlespacing{\chapter}{0pt}{-50pt}{0pt}
\titlespacing{\section}{0pt}{2.5ex plus 1ex minus .2ex}{1.3ex plus .2ex}
\titlespacing{\subsection}{0pt}{2ex plus 1ex minus .2ex}{1.0ex plus .2ex}
%formato de los títulos principales para cada capítulo(el formato de los subtítulos se indica dentro de cada capítulo
\tableofcontents

\chapter{Intro}
\end{document}

But It doesn't have any sense, before the title I don't want a chapter, my thesis will continues forever :( — , Sep 02 '17 at 13:19

Just use \maketitle without environment center:

\begin{document}
\maketitle

But If I don't use it, title is not centered, am I wrong? I need it to be centered – Sep 02 '17 at 13:23
@HernanMiraola If you do not want to try it, then take a look at the definition of \maketitle in report.cls. There, you will find \begin{center} and \end{center}. – Heiko Oberdiek Sep 02 '17 at 13:27

Just move line 30: \pagestyle{mystyle} ;under \maketitle command and it's centering.

Edit

Remove centering too from \maketitle

great, but there appears a blank page yet, isn't it? I don't want that.. – Sep 02 '17 at 13:22
If for some reason in other cases it doesn't center use \centering before \maketitle and place both inside {} and not \begin{center} and \end{center} – koleygr Sep 02 '17 at 13:27
