NEED HELP! My animator Keeps returning to "Any State", HELP!

Hi, I'm trying to create a simple bomb with a certain behaviour and states. From out of the blue it keeps returning to "Any State". I can't find anything about this, can anyone help?

In this situation, I'm waiting for either the bomb's timer to go off or for it to collide, but it keeps going back to "Harmless", because of the "Any State".
