Bug when creating a new aim offset with kubolt anims


Im trying to create a new anim offset for crouch animations, because kubolt give only blendspace for standing anim.

So im creating a new aimoffset, i can see all my animatiosn in the bottom-right window so skeleton is ok…

I can drag one animation in the blend sample, and has soon as i drop the first animation, the others are red

I can’t remplace the animation with the same one or drag anims to others, it tell me it should be additive, wich is allready additive.
