Attacking normally and attacking with triggerbot are the exact same animation. The reason that it's not happening when you disable it is because you're sprinting. This isn't a bug
You can see in this video that Triggerbot doesn't factor into this at all (although when tested with Triggerbot, the exact same thing happens as with it disabled). When you sprint attack (like you showed during the "vanilla" test), the animation isn't given, but when you attack without sprint, the animation will show.
