# how to remove additional authors from VLDB template?

I am working on a report using the VLDB template. I am getting an extra section called Additional Authors' even though I have given all the authors names on the front page along with the right author name numbers. This is the following code. I am not sure what is activating the additional authors section.

\numberofauthors{4}

\author{
\alignauthor
Lini Thomas\\
\email{lini.thomas@iiit.ac.in}
% 2nd. author
\alignauthor
Amar Budhiraja\\
\email{ambudhir@microsoft.com}
% 3rd. author
\and
\alignauthor Satyanarayana R Valluri\\
\email{satya.valluri@oracle.com}
% 4th. author
\alignauthor Kamalakar Karlapalem\\

}


Basically the problem is with vldb.cls file. In vldb.cls file, change :

\def\addauthorsection{\ifnum\originalaucount>3

\def\addauthorsection{\ifnum\originalaucount>6
