Make Transition button disappears after adding one transition.

Unity Engine
1

I added the Idle, Run and JumpAttack animation clips to the animation controller. Then I made a transition from Idle to Run. After that to make a transition from Idle to Jump Attack but the make transitions had already disappeared from the Idle animation clip. I could make a transition from Run back to Idle state but after that the make transition button from Run animation clip also disappeared.

I am using Unity Editor Version 2020.3.32f1 LTS on Windows 10
