Animation gets cancelled when using 2 buttons

I have setup aiming with the right click and only when it is held can the player use left click to fire.

The issue is when I left click (while right click is held) my fire / recoil animation does not happen and instead my character goes to the defualt pose as if I am not pressing anything at all.

Please help, I will attach screenshots of my event graphs and hopefully we can resolve this together.

(EVERYTHING I HAVE HIGHLIGHTED IN YELLOW IS FOR THE FIRE WEAPON, EVERYTHING YOU SEE ABOVE IS FOR THE HOLDING OF RIGHT CLICK FOR AIMING WHICH WORKS PERFECTLY FINE, BOTH MONTAGE ARE SETUP AND HAVE THE SOCKET FOR THE UPPER BODY WHICH I HAVE SETUP IN THE ANIMGRAPH, IF YOU REQUIRE ANYMORE SCREENSHOTS L

Thanks in advance.

Are you applying the Montage in the Anim Blueprint?
