Paper 2D action animation not working while on ground

So I am a noob, I followed the tutorials for doing the flipbooks and event graphs. So now my character and idle, run, jump, fall using flip books. However, I just created an attack animation with flipbooks and then in event graph just did right mouse click that connects into a set flipbook which is supposed to play my attack animation. When I try to see if this works in the game it doesn’t override my idle animation or ill try to run and then right mouse click and still nothing happens. However when I jump or am falling and press right mouse click then it plays the attack animation perfectly… SO why does it only work when my character is in the air??? Any information will help. thank you
