Why is the wrong path to tpl formed in opencart?

Question

opencart

The error code itself:
2018-12-06 21:46:04 - PHP Notice: Error: Could not load template /home/grandeby/maximal.by/catalog/view/theme/default/template/default/template/product/product .tpl! in /home/grandeby/maximal.by/system/storage/modification/system/library/template/php.php on line 23
default/template - repeated twice. Where can you dig to find the error?
The error refers to this file, but everything is fine there, because other modules are loaded without problems.

namespace Template;
final class PHP {
  private $data = array();
  
  public function set($key, $value) {
    $this->data[$key] = $value;
  }
  
  public function render($template) {
    $file = DIR_TEMPLATE . $template;

    if (is_file($file)) {
      extract($this->data);

      ob_start();

      require($file);

      return ob_get_clean();
    }

    trigger_error('Error: Could not load template ' . $file . '!');
    exit();
  }	
}

See what is the path to the template in the product/product controller
