Cannot do choke submission ufc 4 career

Hi, 

I don’t know if I’m just stupid or it’s not working, but In career during a match I am not given the option to do choke submission. I can only the left joystick ones like the ground and pound, get up and joint submissions. 

however when I am in the training camps it automatically makes me do choke submissions, so I’m super confused that am I doing wrong.

p.s I’m on a ps4 and when I do to take them down I use L2 and square to bring them to ground 

cheers for the help
