Two copies of actor blueprint with sequencer

While my sequence is open, there are two copies my blueprint in the outliner. They’re both there when I view the sequence as well as when I render a movie.

I’m adding the BP as an actor to the Takes Recorder because I want its buoyancy behavior to be recorded. The copy in the sequencer works as far as its buoyancy, but then a frozen copy (the original in a way) is sitting there.

What am I misunderstanding? Thank you.

If I manually reposition the two frozen copies out of frame (after capture but before render), it works out. But this is a silly solution.
