Bio::Graphics::Panel, add_track, add_feature repeating labels

[Mark Lewis-6]

Hello,

I'm using the above mod to add glyph tracks and contained features to a
panel object; for each glyph, the label for some reason is being written
twice, once above the other eg:

CCAATBOX1
CCAATBOX1
+-----------+
|           |
+-----------+

The code I'm using is:

## PANEL DECLARATION

$panel = Bio::Graphics::Panel->new(-length        => $zoom,                
# length of panel
-width         => $imgWidth,               # physical width of img in px
-pad_top       => 10,                      # padding
-pad_bottom    => 10,
-pad_left      => 10,
-pad_right     => 10,
-bgcolor       => $bgColour,      
-grid          => 'true',
-gridcolor     => '#cccccc',
-gridmajorcolor => '#888888',
-all_callbacks => 'true',                  # for coloured URE bars
-offset        => $offset,                 # decremented by $zoom at loop
end
);

## TRACK DECLARATION
$track = $panel->add_track(
                              -glyph     => 'segments',
                              -linewidth => 2,
                              -height    => 8,
                              -fontcolor => $txtCol,
                              -label     => 1,
                              -description => 0,
                              -bgcolor   => sub {
                                 my($feat)  = shift;
                                 my($score) = $feat->score;
                                 return ($cols[$score]);
                              },
                              -bump        => 1
                    );

## GLYPH ADDITION
my($feature) = Bio::SeqFeature::Generic->new(-display_name => $SEQname,
-score        => $SEQcol,
-start        => $SEQstart,
-end          => $SEQend,
-tag          => { new => 1,
                                                           id => $featureId }
);
$track->add_feature($feature);

where $SEQ\w+ are passed from my subsequence source.

Can anybody perhaps comment on what I might be doing wrong in these
statements which might cause the above symptom?

Many thanks
Mark
