User creation problem through Delimited driver in IDM 4.8

Hy Team,

i am trying to create the user by the use of delimited driver. when i put the .csv file in the input path , only the first user in input file is created in ID vault although i put the multiple user value but the driver will check only the 1 st row value .it dont check the other values.i put the unique association value for each unique user.
