This seems related to ComfyUI-AnimateLCM rather than my sampler. I unfortunately can't help with this one as I have no experience with AnimateLCM.

However, to determine whether this might be a compatibility issue between my node an AnimateLCM somehow. Please test if this problem also occurs with the default LCM sampler that comes with comfy.

Doesn't seem to be anything here for me to do, so closing.
