Set Playback Position for Flipbook always 0

Hi!
I use the function Set Playback Position for my blueprint and the result is always 0.
I know because I do a print string and it always shows 0.

Is there any secret or trick to make Set Playback Position to work?

With more tests and debug Ive found that I cant controle the flipbook position from my level blueprint.
But I could control if I shoot the event from the the blueprint where the flipbook resides.

I dont know why thats happening.

The Set Playback Position function cant work with Event Tick?

Resolved:
to use with Event Tick we should use Set New Time and not Set Playback Position.
