Can't use medium punch or kick

I just bought Killer Instinct on Steam and I went into the training mode to try it out, but I was not able to use medium punch or medium kick. I have tried to change the bindings for mp and mk but it doesn’t no matter which button they are bound too. There is nothing wrong with the buttons since they work fine in the menus. I’m using a Madcatz TE if that does help.
