Montage Animation Problem

Hi, I added an animation to my third person character.
My problem is, whenever I press the button which plays the animation, it plays the animation, however it doesn’t stop in the end, and simply returns to idle/running.
My question is, how do I make it so that the moment I press the button it will play the animation and stop by the end of it, and whenever I release the key it will return to idle/run?

anyone can help?

Is this the preview that’s repeating or your actual game render?
I’m a total noob to UE4 Engine( and I find the fact that this topic hasn’t been answered since this morning to be discouraging. Is there a more active place to ask questions?) but I’ve noticed that animations will keep looping while you’re creating in certain modes and their sub-modes in the editing tools.
