I see the same problem when I put the following in my minimal-org.el

(custom-set-variables
 '(org-latex-classes (quote (("beamer" "\\documentclass[presentation]{beamer}" 
("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") 
("\\subsubsection{%s}" . "\\subsubsection*{%s}")) ("chapter" 
"\\documentclass[11pt]{report}" ("\\chapter{%s}" . "\\chapter*{%s}") 
("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . "\\subsection*{%s}") 
("\\subsubsection{%s}" . "\\subsubsection*{%s}")) ("article" 
"\\documentclass[11pt]{article}" ("\\section{%s}" . "\\section*{%s}") 
("\\subsection{%s}" . "\\subsection*{%s}") ("\\subsubsection{%s}" . 
"\\subsubsection*{%s}") ("\\paragraph{%s}" . "\\paragraph*{%s}") 
("\\subparagraph{%s}" . "\\subparagraph*{%s}")) ("report" 
"\\documentclass[11pt]{report}" ("\\part{%s}" . "\\part*{%s}") ("\\chapter{%s}" 
. "\\chapter*{%s}") ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . 
"\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}")) ("book" 
"\\documentclass[11pt]{book}" ("\\part{%s}" . "\\part*{%s}") ("\\chapter{%s}" . 
"\\chapter*{%s}") ("\\section{%s}" . "\\section*{%s}") ("\\subsection{%s}" . 
"\\subsection*{%s}") ("\\subsubsection{%s}" . "\\subsubsection*{%s}")))))
)

I did encounter another curious problem though.  When in the customise
buffer I try to add a new class, I get a customize interface similar to
what is shown below.

  [INS] [DEL] List:
              LaTeX class: beamer
              LaTeX header: \documentclass[presentation]{article}
              Choice: [Value Menu] Heading:
                numbered: \section{%s}
              unnumbered: \section*{%s}
  [INS] [DEL] List:
              LaTeX class: article
              LaTeX header: \documentclass[11pt]{article}
              Levels:
              [INS] [DEL] Choice: [Value Menu] Heading:
                            numbered: \section{%s}
                          unnumbered: \section*{%s}
              [INS] [DEL] Choice: [Value Menu] Heading:
                            numbered: \subsection{%s}
                          unnumbered: \subsection*{%s}
  [...]

As you can see, there is no way to add deeper sectioning entries for the
new entry (beamer).  I worked around it for the moment to proceed with
my test, but I find this very curious indeed.
