I was travelling to Nepal on a flight and my passport was stamped. I returned back to Calcutta on a train and I didn't get a stamp when crossing the border.
Is that a problem?

As this answer confirms (based on the Government of Nepal website), there is not even a need for an Indian citizen to carry a passport when visiting Nepal. Therefore there is no reason why a stamp would be required when crossing any of the borders you crossed.
So no, this should not be a problem.
