    $this->defaultLanguage = $this->getLanguageBaseName($this->defaultLanguage) . ' NOT CHANGE FOR DEFAULT LANG ';

line 350
foreach ($this->attributes as $attribute) {
$value = $defaultLanguage ? $owner->$attribute : $this->getLangAttribute($this->getAttributeName($attribute, $lang));

to

            if ($this->getLangAttribute($this->getAttributeName($attribute, $lang)) != '') {
                $value = $this->getLangAttribute($this->getAttributeName($attribute, $lang));
            } else if ($this->getLangAttribute($this->getAttributeName($attribute, $defaultLanguage)) != '') {
                $value = $this->getLangAttribute($this->getAttributeName($attribute, $defaultLanguage));
            } else if (isset($owner->$attribute)) {
                $value = $owner->$attribute;
            } else {
                $value = '';
            }
