Help Me With Movement Animation?

So, here's my current event for the movement animation :

With this event, the animation works perfect. But, the problem is when I quickly press left & right, the animation failed to mirror. For example, when the player move to the right, and then quickly I change direction to the left, the player walk to the left but the animation is still not mirrored a.k.a moonwalking.

Now, if I do this :

The moonwalk problem is gone, but the animation won't stop when I'm not moving the character.

Any suggestion?

You need to trigger when you pressed a key and when you release any key you back to 'idle' animations.
