Replay Problem with Embedded Sequencer Animations

I was learning to create an interactive door Blueprint with embedded sequencer animations (open and close animations). I referred to the instruction here:…/ActorSequence. When I test run it in the editor, the two animations were correctly played back once. In the following playbacks, they only showed the beginning and ending frames and skipped all other frames. The door just jumped to the open or closed state without the rotation movement being animated. I was wondering if that is normal due to the actor sequencer plugin still under development or there is something I need to take care of to make things work. Thanks!

I am attaching a screenshot of the BP event graph. The whole assets I used can be downloaded here:
