Match bonus time not working properly

I'm playing a CL game. Right at the beginning of the game, I used the extra bonus of "Condition" but is decreasing the time very slowly instead of the 20' match time than usual. I'm already in the 55' and is still like 1/3 left... so looks like from the beginning of the game is going to last the whole game.

So the game just finished and I can confirm that the "Extra bonus" or sideline instruction lasted the whole game. Just one. Played on iPad.
