I'm sick to death of this Triumph!!!

I have 3 generals who have been hailed as Imperator by the troops, and they got a message saying they had earned a Triumph. So when I took my generals back to Rome expecting to see a flashy cut scene with my general looking decidedly and rightfully chuffed with himself for conquering all of Greece/Gaul/Germania, nothing happened.

I don't understand why the Senate won't let me have it when they say I deserved it!
