Remove the ‘Employee Selection’ from the [Reports] tab criteria as it is superfluous. By default the “Custom” option already selects all Employees which effectively renders the “All Employees” option redundant and at the same time allowing the user to immediately select which (if any) Employees need including and if necessary they can use the ‘header’ check box to select/unselect all Employees. This has the added benefit of displaying the employees to the user before running the report which I feel provides more transparency on what is included along with the granular control for the user.
