What part is wrong? If you look at the Assigned data, the total number of tickets assigned to all agents is equal to 548. If you look at the tickets assigned to all the departments they equal 548 as well.
If you look at the Closed data, the total number of tickets closed by all agents is equal to 1,130. If you look at the tickets closed in all departments they equal 1,130.
Seems accurate to me.
Cheers.
