Issue on Import with action "Update existing records&qu

Is there an issue on Import with action "Update existing records"? I have records with Different Status and I used import action Update existing records for sending them into Archived or Sold with the trigger running after update, if it found the new_used field with "U" (U - is in the xls) then it will change the status with Archived or Sold. What happens is that it changes the status into default Status "New". What confused me is that it runs into normal edit and save. if("{!new_used#value}" == "U") { if("{!status#code}" == "newaddition") { return "archived"; } else if(("{!status#code}" == "changerequest" || "{!status#code}" == "running") && "{!final#code}" == "no") { return "sold"; } else { return "{!status#code}"; } } else { return "{!status#code}"; } Thanks.
