Created Signal on mission controller not visible under tab mission tab components property

I have created one Boolean signal on mission controller, and want to trigger mission based on this signal value, but when i am trying to select my signal from dropdown list, i am not able to find my created signal in mission controller drop down list. Why is this so?

Hi, have you tried selecting the Mission Controller in the “Component” dropdown list ?

now i got it automatically i just unselected2-3 times and selected again

Thankss
