Hello 

The only possible reason would be that KMC ,Manipal might have opted out their affiliation with Karnataka Examination Authority but KMC,MAngalore would still have been a part of KEA,2018.

To clarify the doubt its better you contact the university/authorised people of the university and ask them about the same.

This may also be due to the reason that the university has forgotten to mention KMC,Manipal in the list by mistake ,so its better to confirm from them directly.

Thank you
