[Tex/LaTex] Problem of formatting bibliography with one beamerposter theme

beamerbeamerposterbiblatex

I am using the beamerposter theme beamerthemeZH.sty now to generate my poster. The theme is downloaded from the project latex-beamerposter on GitHub. The theme beamerthemeZH.sty is in the direction example/03/. I am wondering whether anybody knows this beamerposter theme or has used this before.
My problem is, when I use bibtex to format the bibliography, information of bib items is too much for me and I did not find a suitable bst style. Then I am trying to use biblatex to format bibliography. Here is my MWE:

\documentclass{beamer}
\usepackage[orientation=portrait,size=a0,scale=1.4,debug]{beamerposter}
\mode<presentation>{\usetheme{ZH}}
\usepackage{chemformula}
\usepackage[utf8]{inputenc}
\usepackage[german, english]{babel} % required for rendering German special characters
\usepackage{siunitx} %pretty measurement unit rendering
\usepackage{hyperref} %enable hyperlink for urls
\usepackage{ragged2e}
\usepackage[font=scriptsize,justification=justified]{caption}
\usepackage{array,booktabs,tabularx}
\newcolumntype{Z}{>{\centering\arraybackslash}X} % centered tabularx columns
\sisetup{per=frac,fraction=sfrac}
%%%Lines form here and before \title is added by myself%%%

However, only the first bib item show the sequence number 1, the following ones do not have a number before the bib item.the pdf file
Could you please tell me how can I fix this problem? Any help would be much appreciated!

The problem is caused by the \justify, which the ZH beamertheme adds to the definition of the block environment. If this is removed the bibliography is numbered:

\documentclass{beamer}
\usepackage[orientation=portrait,size=a0,scale=1.4,debug]{beamerposter}
\usetheme{ZH}

\setbeamertemplate{block begin}{
    \setlength{\mylength}{\textwidth+2ex}%
    \vskip2ex
    \begin{beamercolorbox}[ht=2.8ex,dp=2ex, wd=\mylength, center,rounded=false,shadow=false,leftskip=1cm,colsep*=0ex]{block title}%
        \usebeamerfont*{block title}\centering \insertblocktitle
    \end{beamercolorbox}\vskip-9pt%
    {\ifbeamercolorempty[bg]{block body}{}{\nointerlineskip\vskip-0.5ex}}%
    \usebeamerfont{block body}%
    \begin{beamercolorbox}[rounded=false,shadow=false,center,wd=\textwidth,]{block body}%
        \ifbeamercolorempty[bg]{block body}\vbox{}%
        \begin{minipage}{0.96\textwidth}\vbox{}%
%       \justify
        }
