import of Multiple user request template, puts junk value in request fields

Hi All,

I want to modify multiple users, for which i have filled the template(create user template) in fields USER  ID, MANAGER, FNAME, LNAME, EMAIL and USER TYPE. i do not want to fill other fields, as they are not required. There is no other template available.

But after import junk/garbage value appears, as below. Could you suggest on the solution

Regards
