Biblatex bibliography in beamer does not work (name of the articles in bold)

Question

Using biblatex I don't obtain the name of the reference but the name of the article - in the .bib - file in bold.

Here's my code:

\documentclass{beamer}
\setbeamertemplate{bibliography item}{\insertbiblabel}

\mode<presentation> {\usetheme{Madrid}  
    }

\usepackage{graphicx} % Allows including images
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule in tables

\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
\usepackage{hyperref}
\usepackage{pgfgantt}
\usepackage[backend=biber]{biblatex}
\addbibresource{presentation.bib}

%   TITLE PAGE

\title[Short title]{Proyecto de Tesis: Holografía y sistemas integrables} % The short title appears at the bottom of every slide, the full title is only on the title page

\frametitle{Resumen}

Las p-formas autoduales se definen en dimensión $d=2(p+1)$, donde $p$ es par . Su caso más sencillo, con $p=0$, corresponde al bosón quiral . Esta ecuación aparece como un caso particular de la denominada ``jerarquía de KdV''. Dicha jerarquía se puede formular como una acción de Chern-Simons en una dimensión extra, escogiendo condiciones de borde adecuadas para la conexión. El objetivo de esta tesis es generalizar esta construcción con el fin de generar sistemas integrables para p-formas en dimensiones superiores, con aplicaciones a supergravedad en seis dimensiones \cite{Marcus:1982yu}.

My purpose is being able to use the \footfullcite command. I've read this and this articles but I don't know the problem.
