My eyebrows are tilting but not moving.

Hi. I am new to Character animator and I came across the problem of eyebrows not moving. I renamed them +Left or right eyebrow, added them to the head folder, added behavior, and still nothing. I tried adding them to different folders, renaming them, played with handles (idiotically) and the only thing that helped was to add them to the +Eye folder. But the problem is, that the eyebrows disappear when the character blinks. But they are moving. So help, I really don't know what to do to fix this.
