Aura is in the wrong spot to activate her moves. The dots at the top of the move details show where she need's to be (in white) and who it will affect (blue dots are allies, red dots are enemies). it tripped me up, too.
Most of her skills will work at Rank 1 or 2 (far right or mid right) . If you can't do anything but wait, she might have a condition that disables them, like arms bound by something. Also, it is possible to unselect all skills in the character details.
