Level Sequencer Not Showing Actors

During my first map I used Level Sequencer to animate my objects. Everything worked fine. Now that I have started other projects, I cannot animate anything. Every time I add an actor, I just get a blue bar on my timeline. Invisible … Even when I go back to my first map and look at my level sequencer everything is offset and though my key frames are still there, the actors are still invisible. No matter what actor I add to my level sequencer, I just get a solid line with no actor or keyframes. I can’t do anything.

Could it be filters? Can't add actors in the sequencer to animate them - #5 by Max.Chen
