Marker Notification is repeated after resuming timeline

Probably same problem with this thread:

Notifications are pushed after resuming Playable

I am trying to call certain methods using timeline and custom markers (Notifications), as demonstrated here. The goal is that each marker notifies the manager script to start a new wave of enemies that have to be defeated by the player before moving on. For that matter, I am using _playable.Pause() (where _playable is a PlayableDirector component) when a marker is reached and the corresponding notification received. Everything works to this point, but after beating all enemies I call _playable.…

I’m trying to use Marker Notification for dialogues which pops up at particular moment of the timeline.
After popping up dialogue the player needs to look into dialogue, so I set Signal Emitter that pauses timeline.
And if the player read dialogue enough, push any key and the script resumes the timeline.
But in the testing, when I pushed key and resumed, the dialogue already passed pops up again.

This means Marker Notifications are called after passed frame if I pause & resume timeline.
I reproduced this problem in small timeline test scene and attached here.
If you hit play and passed marker, first “Notify Sent” log appears.
After that you pause the timeline and hit play again, second “Notify Sent” log comes in.

Is this a bug or it’s meant to be? How can I avoid this double notification?

Same problem here. I am using a custom marker instead of signals, but the result is the same. I’ve solved it by adding a bool ‘AlreadyNotified’ to the marker, setting it to true in the ‘OnNotify’ method of the reciever, so that it’s ignored after the first call, but I also wonder if this behaviour is intended, and why.
