Oh nice! Thanks Erika! I never saw any changes when using CTRL+L in the past so I didn't consider it at all.
I tried it when I got back to work and CTRL + L doesn't work. I know in this particular case Ctrl+Shift+L will work but in the cases where there's no keyframe, CTRL+L also doesn't work.
Noticing that CTRL+L is keying Deform on mesh and visibility on Region. That seems to be the issue and almost everything used is mesh for this project.
