How to method 2 blend space animation for character on jump from height loop?

I create 2 blend space animation to link the animation, but I can do it on [Idle/Run] and [Jump]. Is mean [Idle/Run] blend animation with Direction and Speed, and [Jump] have blend by Speed. Also I want to [Jump] link to [Falling]. But I can’t do that, don’t know why.
***** Animation In Blend Space Animation and Set Transform *****
Blend space animation 3D
[Idle/Run] : - Idle {speed 0 Direction 0}
- Walk Forward, Backward {speed 200,-200 Direction 0,0}
- Walk Strafe Left, Right {speed 200,-200 Direction 200,-200}
- Jog Forward, Backward {speed 400,-400 Direction 400,-400}
- Run Forward, Backward {speed 600,-600 Direction 0,0}
- Run Strafe Left, Right {speed 600,-600 Direction 600,-600}
- Jog Strafe Left, Right {speed 400,-400 Direction 400,-400}

Blend space animation 1D
[Jump] : - Standing Jump {speed 0}
- Jump Forward, Backward {speed 200,-200}

[Falling]: - Falling Idle {speed 0 Gravity 0}
-Falling loop {speed 150 Gravity 250}
-Flying {speed 300 Gravity 500}

***** Event Graph *****

[Event] Blueprint Update Animation -> Isvalid (Character Blueprint is Input Object) -> set Direction -> Speed -> Cast To Character Object -> Set IsCrouch -> Set IsFalling
^ ^ (link to Speed)
| \
(Character Blueprint is Input Object) -> Get Velocity (Dot) Get Actor Right Vector (Dot) Get Actor Forward
|
v
Character Movement -> IsFalling -> Set IsFalling
[Try Get Pawn Owner] -> (link to Cast To Character Object) -> (link to Set Is Crouch)

***** And How to setting event graph for calculate character height from transitions to link Falling blend space animation?
