Why notifiers called twice

Hi everybody! I have a problem which seems to be bag in UE5.
I have notifiers in animation sequence ( when foots of character step floor ) .
And if i use this animation in Level Sequence and via slot pass it to animation blueprint , notifiers calls twice. It looks like first they calls at animation track in Level Sequence , and repeat call in animation blueprint with slot. If i disable animation blueprint it works good. And no way to fix it , except manually disable second notifier through checking variables in Received Notify function. (there it is also very difficult to do this, since global variables are not available in Anim Notify , so you have to do Cast to blueprint of actor) Check the box on “Skip anim notifiers” didn’t help. It works only if we don’t use animation blueprint.
