Spawned Cameras Missing In Sequencer

Hi everyone, so I opened my sequencer and now I no longer see my spawned cameras inside of the sequencer. I was wondering if there is a way to bring them back? I know I can right click the camera tracks and find the class of the object again, but I was trying to do it for all 100 cameras in my scene. Right now it’s looking like have to go one by one to the cameras. Is there a way to do it all at once?

Also why did the spawnable cameras go missing in the first place???

Just happened to me too
