Display module not working

Diplay module not working on timeline advance display.
Something changes between yesterday and today. All my display modules that I made yesterday is showing fine in my timeline window, but all the new display module i put in today just wont show in timeline but worked on camera only.
I use this alot when animating because i can isolate every single character and bodyparts on timeline and camera, which makes animating so much easier.

I think its a bug, but it only just start happening today though…

???

Please select "Display All"option.
“Scene-Default Display-Display All”

Nevermind, its one of those weird bugs.
I works just fine on different files.

How are you viewing the Display modules at all, are they tagged?
