Problem to animate in Moon Plugin

Hello , I try to animate 5 NPCs but the third is problematic, idk why he doesnt want to move, someone can help me ?

Looks like he is moving. You are moving him up and down, what do you mean?

I mean, when I release my click, he resets

You didn’t move your line, you need to move your line to the time that will suit your animation and move the npc backdown. Right now you have no new keyframes. I’m guessing your new to animating? Follow this:
