You haven't mentioned whether your rank is displayed. This is important because if your 12th marks are not being displayed ideally you should not have a rank displayed as well. There are 3 reasons why a rank might not have been assigned in KCET:

1. 12th marks missing
2. You must have marked the code inversion wrong
3. Revaluation of your 12th means your marks must have changed and a new rank needs to be assigned.

So please try uploading your 12th marks again and you will be assigned a rank. But if you rank is being displayed but your QE marks are not showing up, please write a mail to the helpdesk at: keauthority-ka@nic.in from your registered Email id with the screenshot of the QE marks not being displayed but the rank being displayed. They will look into it.
