Multi thread animation blueprint and anim notify in multiplayer project

Hi! I have implemented multi thread and ALS system in a multiplayer project. It works fine but I have an issue with anim notifies: I have noticed when a multicast function fires a montage with Anim notify, the anim notify is triggered once in the client (correct) and twice in listened server. The multicast function is ok, it occurs with every montage and animations, the only fix I have founded is unchecking “Use Multi Threaded Animation Update” on AnimInstance class settings, but I don’t want to loose multi threading! Is there some further configuration to do or another way to do that? Thanks in advance!
