Some animation database is not often selected fast

Hi everybody, just working on motion matching chooser and animation database.
I set few animation database for locomotion, jumping and crouching at the moment.

About crouching, often the crouch animation doesnt start. despite in the CP_character works perfectly moving camera. I have to move the mouse to see my character changing animation from standing position to crouch

Any possible idea?
Many thanks

found the solution:
in the PSS I selected the root of the character in the index2. It seems to be working properly adter pressing the button to crouch.
