Import -> Discrepancy in Mapping field

There are lots of discrepancy in mapping field
Mapping field before saving shows different name and different after saving data

Eg :1) Login Employee status
2)Add Employee last class when mapped -> System wont allow to import -> "Shows Duplicate plan design identifier"

Also there are many export related field in import template -> Need to remove all those
Eg : 1) Add Employee Payroll schedule
2)Employee Full name 1 - QA ASML for hspl(LB)
