Same thing happened to me even though I will get several nit and iiit through last year cut off

It happens because the choice of field and institute, you have filled is not available for your rank. It is due to the reason that your rank is low as compared to your choices. Since, you have not been allotted any seat in round 1 of JOSAA, you have to patiently wait for round 2 results. If you want to change your choice, you can do so right now. There is no need to panic about it.

I hope this answer clears your query.
