Why can't i make more than one transition from my default state?,why am i unable to do more than one transition from my default state?

hi
I did like in this video :

The 8 of 14 at 4.37 but the guy is able to do a transition from the default state to playerHit state

Me I just can’t because the menu make transition doesn’t appear
But it did work for playerChop…
I don’t understand .

can you help me please?,

The only solution i found is to: don’t use animator

So i did a script and i ended up with something like:

const string PLAYER_IDLE = “Player_Idle”;

if (inputHorizontal > 0)
{
ChangeAnimationState(PLAYER_IDLE );
}

Well you get the idea… and it works at least to make it move but i didn"t try it to make it attack yet with this .
I’m thinking of playing with something like

if Input.GetKeyDown (“doesn’tmatterforexemple”)
{ ChangeAnimationState(PLAYER_CHOP);
}

I hope it will work.
Don’t hesitate if u have any advice or if that transition menu bug happened to you too please
