Multiple characters on slide not allowing different triggers

Hi everyone, 

I've just stumbled across an issue that has not happened to me before! I have 3 characters on a slide that act as a menu for the learner to pick from. They are all supposed to jump to a different scene, however if I change the trigger for one of them, they all seem to change!

I've tried deleting them and adding them in again but it makes no difference! Any ideas?!

Thanks :)
