Settings aren't updating properly

[takdzwiedz]

Good day,
My deployed open-source platform does not conduct settings update properly. System notifies that something went wrong without details. It refers to Settings: general, style and registration. I can add geographic area or edit Terms & Conditions as well as I can add proposal without problem.
When I try to save new settings I have following answer from request:

PATCH https://wspoldecyduje.click/web_api/v1/app_configuration 422

{"errors":{"settings":[{"error":{"fragment":"#/","error":"AdditionalProperties","human_message":"The property '#/' contains additional properties [\"user_confirmation\"] outside of the schema when none are allowed in schema 21a6d023-6dc2-5182-a016-a0c94a55d452"}, ...

You can check it is live.

Do you have an idea what the reason is?
Thanks

I believe it's the same reason as here #3606 (comment)

I'll let you know as soon as it's fixed.
