Ok I’ve managed to narrow it down to a bizarre problem with the stylesheets which are loaded from my themes functions.php file. If I remove one of the links to the stylesheets, one of the numbers disappears.
Here is the code below:
/*-----------------------------------------------------------------------------------*/
/* Register Core Stylesheets
/* These are necessary for the theme to function as intended
/* Supports the 'Better WordPress Minify' plugin to properly minimize styleshsets into one.
/* https://www.ads-software.com/extend/plugins/bwp-minify/
/*-----------------------------------------------------------------------------------*/
if ( !function_exists( 'st_registerstyles' ) ) {
function st_registerstyles() {
// Set a dynamic version for cache busting
$theme = wp_get_theme();
if(is_child_theme()) {
$parent = $theme->parent();
$version = $parent['Version'];
} else {
$version = $theme['Version'];
}
$stylesheets = '';
// register the various widths based on max_layout_width option
$maxwidth = of_get_option('max_layout_width');
if ($maxwidth) {
// load the appropriate stylesheet
$stylesheets .= wp_register_style('skeleton', get_bloginfo('template_directory').'/css/skeleton-'.$maxwidth.'.css', array(), $version, 'screen, projection');
} else {
//fallback to original for legacy theme compatibility
$stylesheets .= wp_register_style('skeleton', get_bloginfo('template_directory').'/css/skeleton-960.css', array(), $version, 'screen, projection');
}
// Register all other applicable stylesheets
$stylesheets .= wp_register_style('layout', get_bloginfo('template_directory').'/css/layout.css', array(), $version, 'screen, projection');
$stylesheets .= wp_register_style('formalize', get_bloginfo('template_directory').'/css/formalize.css', array(), $version, 'screen, projection');
$stylesheets .= wp_register_style('theme', get_bloginfo('stylesheet_directory').'/style.css', array(), $version, 'screen, projection');
// hook to add additional stylesheets from a child theme
echo apply_filters ('child_add_stylesheets',$stylesheets);
// enqueue registered styles
wp_enqueue_style( 'skeleton');
wp_enqueue_style( 'theme');
wp_enqueue_style( 'layout');
wp_enqueue_style( 'formalize');
}
add_action( 'wp_enqueue_scripts', 'st_registerstyles');
