This is a good catch. See
http://www.calemeam.com/apps/mantis/view.php?id=46To apply the fix manually:
1. Edit CalemMsg.properties (under CalemEAM/client/lang)
Replace line 624:
cost_employee = Employee
with
cost_employee_labor = Employee
2. Got to CalemEAM/bin, run deploy.bat build
3. Relogin, this should be fixed.
Alternatively one can fix this issue by going to dropdown design (from admin's data design) and set the text for the empty note in the dropdown tree to 'Employee labor'.
