Here is my tweak. Please backup your file before doing anything.
1. Copy this function to file (inside class ContentFilterHelper)
plugins/jamegafilter/content/helper.php
protected function filterText($text, $lang) {
$db = JFactory::getDbo();
$query = "SELECT sef FROM `#__languages` WHERE lang_code = '$lang'";
$lang_code = $db->setQuery($query)->loadResult();
if ( strpos( $text, '{lang' ) === false ) return $text;
if ($default !== false && strpos( $text, '{lang '.$lang_code ) === false) {
$lang_code = $default;
}
$regex = "#{lang ".$lang_code."}(.*?){\/lang}#is";
$text = preg_replace($regex,'$1', $text);
$regex = "#{lang [^}]+}.*?{\/lang}#is";
$text = preg_replace($regex,'', $text);
return $text;
}
- Then if you want to apply to text custom field, do like this

- For list, checkbox, radio

If you not familiar with code, i can help you.
