Jump animation looping when jump key is held (without really jumping)

I recently started using ue4 and I made a project with a tutorial.
So, when you press once jump key jump sequence starts, animation plays and it’s all ok
When you release it goes back to the idle stand animation (or walk, or jog)
The problem occurs when you hold the jump button, character doesn’t really jump but the animation plays again and again,
could you tell me how to prevent this from happening?
I want my character to jump once even if I hold the jump button, no animation playing again.

sounds like your animation blueprint… either the transition rule or the "is in air?’ part
