What's the proper way to reference and destroy gameplay cue notify actors?

Ah, it’s a networking thing,

Even if I play alone, If i play as a “client”, this is where the error occure,
When I play in StandAlone I see no bugs.

Nice, this is how I was applying the effect

Using this

This website

state that :
If a GameplayCue was Added locally, it should be Removed locally. If it was Added via replication, it should be Removed via replication.

Could it be that my Cue is added locally but the effect is turned out by the server ? unless I’m using a different period in which case the cue is removed locally first ?
