[Tex/LaTex] How to remove extra space after volume number in References section

apa-stylebibliographiesspacing

When I compile my manuscript, in the references section extra space is added after the volume number. My corrector told me to remove it, but the problem I don't know how to remove it.

MANUSCRIPT.TEX

\documentclass[man]{apa}
\usepackage{graphicx}
\usepackage{rotating}
\usepackage[dutch,english]{babel}

\makeatletter  
\newcommand{\rmnum}[1]{\romannumeral #1}  
\newcommand{\Rmnum}[1]{\expandafter\@slowromancap\romannumeral #1@}  
\makeatother 

\title{...}
\author{...}
\affiliation{...}

\abstract{...}
\acknowledgements{...}  

\shorttitle{...}
\rightheader{...}
\leftheader{...}

\begin{document}  
\maketitle    

\section{...}    

\bibliography{References}

\end{document}

References.bib

@ARTICLE{BergCollier1953,
   author  = {Berg, I. A. and Collier, J. S.},
   year    = {1953},
   title   = {Personality and Group Differences in Extreme Response Sets},
   journal = {Educational Psychological Measurement},
   volume  = {13},
   pages   = {164--169}
}

@ARTICLE{BergCollier1953,
   author  = {Berg, I. A. and Collier, J. S.},
   year    = {1953},
   title   = {Personality and Group Differences in Extreme Response Sets},
   journal = {Educational Psychological Measurement},
   volume  = {13},
   number  = {X},
   pages   = {164--169}
}

OUTPUT

Berg, I. A., & Collier, J. S. (1953).
Personality and group differences in
extreme response sets. Educational
Psychological Measurement, 13 ,
164–169.

Berg, I. A., & Collier, J. S. (1953).
Personality and group differences in
extreme response sets. Educational
Psychological Measurement, 13
(X), 164–169.

The extra space is added on every reference (see the X after the volume number).

Normally where the X stands a volume number is entered, like this 10(3). When I enter this volume number the comma is place directly after the 10(3).

I really hope that someone can help me!

I figured out that I must change apacite.bst. However, I need to find the exact solution.

PART OF APACITE.BST

% format journal, volume, number and pages  
% call with  
%   formatted.pages format.journal.vol.num.pages.check  
%  
FUNCTION { format.journal.vol.num.pages.check }  
{ "journal" journal warning.if.empty  
 duplicate$ empty$  
journal    empty$ and  
volume     empty$ and  
  { pop$ "" }  
{ "\APACjournalVolNumPages{" journal "" connect.check  
  "}{" *                     volume  "" connect.check  
  "}{" *                     number  "" connect.check  
  "}{" *                     swap$   "" connect.check  
  "}"  *  
}  
if$  
}

While updating I fixed the problem by replacing the new apacite.bst by an older version of apacite.bst. I simply downloaded it via Google. This is probably not the best solution, but it works for now :).
