Animation Montage Doesn't Stop Playing

I tried adding a punch animation montage to my project, but if I click once, it will play the whole montage before stopping, I’ve followed epic’s video but it just doesn’t want to work.

I still keep playing around with it, this will always play swing1, which isn’t even triggered anymore, and say goodbye.

As of 4.20.3 seems that it’s still better to use separate montages instead of sections.
Notifies are affected by blend out time and not always fire.
