Inherited collection items for configuration collections with collection inheritance are not stored properly

In the old code, it was the following. If a config page with filled properties. the language pages under this page, will inherit these properties. However, if a property in the language page, which is already inherited should be modified, the author can click on the check box beside it which is called inherited, and uncheck this box, the field becomes editable with the inherited value inside. This was cool "Ziemlich cool". However, in the new editor, this check box that is called inherited cannot be unchecked, which results for a problem for our authors. What is required that it should be like it was before in the old editor wcm.io.config v.0. For more understanding of the problem, please see the attached screenshot.
