Hello there. CRL means that your all India rank without any category being specific i.e. it's being when all the candidates are considered.

GEN-EWS means rank means that it's being category specific for GEN-EWS i.e. candidates who are eligible for this category are being considered in this list.

When you will go for admission firstly your CRL will be considered and if you are not able to grab seat from crl then they will look out for your category I.e. for GEN-EWS rank.
