Ui animation clone

Hey there , I am working on my tps game where I have a ui hud to display the eqipped gun and ammo . I have an ui animation for the switching of gun from rifle to pistol . However when I play the animation there seems to be some error . When the animation is played the ui is making a copy of itself and then playing the animation i.e. one ui with the rifle picture (original) and another ui (clone of the same displayed when animation is played) playing the animation ( rifle changing to pistol ) on top of it . I only want one ui to play the animation ( change weapon picture ) . Can anyone tell me what I am doing wrong and why does two ui another ui appear when animation is played ?
