Why dont play attack flipbook?Seem like everything is on right way

This is my blueprints:


check player is attacking or not,if it is attack then set bool is true and movement state is attack1


I’ve found that if I put a printtext in front of and behind the flipbook, it will print the one in the back first, not the one in the front position,is it a bug?

When i was attacking,it could print texts but no attack animation.But other animations can work well, I dont know why.
Thanks for anyone’s help.
