extra bar

[Arthur Dyck]

Can anyone tell me why I have an extra bar before the double bar?  I don't 
want it.

\version "2.6.0"
global = 
{
        \key g \major
        \set score.timing = ##f
        \set Staff.autoBeaming = ##f
}
\layout {
        raggedright = ##t
}
\header {       
                title = ""
                subtitle = ""
                tagline = ""   
                poet = ""
                composer = ""   
}

upperOne = 
        \relative c''{
        \voiceOne
        \key g \major
        a2 b1 \bar "|."
                }
        
upperTwo =  
        \relative c'{
        \voiceTwo
        fis2 g1
}

lowerOne =      
        \relative c' {
        \key g \major
        \voiceOne
        d2 d1
} 

lowerTwo =   
        \relative c {
        \voiceTwo
        d2 g1
}

        A -- men

                }
                \context{\StaffGroup
                }

                \context{\Score
                barNumberVisibility = #all-invisible
                }
        }


\midi { }                       
}
\paper {

        topmargin = .0\in
        leftmargin = .1\in
        linewidth = 5\in 
        indent = 0
        pagenumber = "no"
        }

Thanks.
