Make sure to have enough read and write access for newly added attribute.

To view attribute values add, update attribute in New_Edit page as well and add some values in data base.

Check is there any condition visibility for attribute and access rules rules for overview page.

Lastly always check changes once run the modeler every time.

Hope this help.
