Matinee sound problem?

Hi, I have a problem when I start my game. I use a lot of matinee for sliding doors and other animations and everytime I prees start (play) all the sound from matinee, start simultaneous for a moment and then everything start working normal. I post here some screenshoots from matinee and level blueprint. I don’t know what kind of problem is. (Can be from matinee or level blueprint).

Somebody know why this happen?

Maybe try removing the sound track from Matinee and use a Play Sound Attached blueprint object instead?
