Tnvelaivaaippu.gov.in — Not able to update degree qualification

To update my degree qualification, I entered all the mandatory fields and when I try to save it by clicking on "Save" button, it throws the error. I provided the error screenshot here. Please find the attached error screenshot without fail.

Also, When I try to update my contact information and qualification, I am getting this same error.

This site have lot of bugs and issues. Nothing is working properly. I had a very bad experience while using this site.

Please try to fix and close the reported bugs as soon as possible. Many input fields are disabled by default, every time I need to inspect those field elements in DOM and enable it which is not expected behavior. So, before releasing the application, please do proper unit testing from developer side
