Why is text not shown on the segements of a Sequences Reel (in storyboard view)

Hello

added a Text(TX) Timeline Fx and typed some text. But this text is only shown in Alt+1 view and
not in Alt+2 view and as well not on the segements of a Sequences Reel …

Why that text is not shown in storyboard-view (in a Sequence Reel) ?

Thank you!

Joe
