Kaggel notebook error: Error displaying widget: model not found

There is only one problem: If I save the notebook, close the kernel, and reopen the notebook the next day and rerun the notebook then I only see the message “Error displaying widget: model not found”. but if I copy-paste this notebook into a new notebook, it just works fine. Is this expected behavior?

It seems to be a kaggle platform issue, you can directly commit your notebook as it won’t cause any issues.
