Sequencer says: The object bound to this track is missing after compiling

Hi,
I am making my first steps with sequencer so I guess, I am missing something.
But I don’t understand, where the problem is.

  • In a blueprint I am adding an *Actor Sequence Component *to move one single component.

  • Opening the sequencer to enter the animation.

  • Clicking the + Track] button and select the component to animate

    • Surprise #1: This doesn’t work as expected and I have to try it several times. No clue, what I am doing wrong

    • Surprise #2: After a few attempts of doing it right, the owning actor is named name522. I haven’t tried it 522 times.

  • Then I enter my animation, which seems to work, when I move the slider

  • After hitting the Compile-button, the actor and component go red and state “The object bound to this track is missing”

I am using UE 4.19.2

Thanks and regards
Christian
