Dear @anu.kivimaki,
thank you for drawing our attention to incorrect data in our online archive. We are constantly working to improve our services and are therefore grateful for your comments. Due to a migration of the system, however, it may happen that certain collections are blocked for processing and corrections can therefore only be entered with delays. We thank you for your comment and your understanding.
All the best,
Annabell
