Hi Deepak,
If you have configured there for me it is not wrong the system has this behaviour. But it is strange because I had the opposite problem, even I had configured there the generation of the financial views/groups/ categories using the excel file didn't work.
If you are going to use the report for upload items for migration you can undone these settings and after uplading configure again .
Other option is undone theses settings and include them in the cProjects user setting ( configure for each user the default task type, phase type...) and not to do it for the user that upload the excel.
Regards
