Wrong override path for BO theme templates

[Quant]

I want to redefine the templates for the default BO theme, for example _PS_BO_DEFAULT_THEME _. '/template / footer.tpl'.
Then in AdminController :: display () the wrong folder paths are retrieved.

        // Check if header/footer have been overriden
        $dir = $this->context->smarty->getTemplateDir(1);//.'controllers'.DIRECTORY_SEPARATOR.trim($this->override_folder, '\\/').DIRECTORY_SEPARATOR;
        $moduleListDir = $this->context->smarty->getTemplateDir(1).'helpers'.DIRECTORY_SEPARATOR.'modules_list'.DIRECTORY_SEPARATOR;
