OMG, I have found the issue is in the DB, I have checked the system attribute and the all have the "backend_type" as varchar while the custom or the new attributes I have uploaded through MAGMI were with a backend_type static. https://ibb.co/hL2yhp

Just update the backend_type from static to varchar and it should save in the backend.
