Updation of Final CGPA

The problem is I am not able to update my final CGPA obtained in my profile’s section of elitmus. Everytime I fill the details in the popped up window , It shows that Graduation College can’t be left blank.

Now since I have already filled the details of Graduation college and ignoring that too there is no option to update the graduation college in the pooped up window , I am not able to update my details.

So please look into this concern as I am getting rejected from my interview applications.
