Sequencer: Changes won't show in the sequencer timeline

Hi, I’m having a problem where whenever I make any changes to my sequencer timeline, like adding animations, they don’t show in the timeline. The timeline doesn’t update unless I close the sequence and reopen it which is very troublesome to do everytime I make an adjustment. Really hoping someone can help me out. I included a photo below, as you can see, the actor is being animated but the animation under the playhead isn’t showing in the timeline.
