Coaches warnings

I play out all of my games in 2D.
Question: Can my assistants get warnings or get me a warning. I did not hit any buttons. I see I get warned. Multiple times in multiple different games. However the other teams coach got warned several times also. At first I thought it was a mistake in the game. But when the other computer AI coach was warned also then I was confused.
So either my assistants caused me to get a warning.... Or it is an error in the game?
