couldn’t apply Variables in a component’s child frame

Hii all!
I did a Boolean Variable and defined it’s default state. In order to apply it into the component‘s child, i clicked the little pentagon icon as supposed to, but i couldn’t fined the Variable in the list. I’ve tried to find it under ‘local variables’ and nothing is there, i search the name of the Variable in the search bar and still - don’t find it… I closed opened agin Figma and it did the helped
Someone face the same issue? How can i fix it?
