Question
All layers disappear when adding keyframe or tween




I have 17 layers of different parts of this character's body under one folder. They're all parented. I want to add keyframe/insert tween but if I do so, every other layers will disappear. Plus, I moved the playhead to 30 (1s) and tried to make some changes with the wrap tool (W) there, but the playhead would move back to 0s.
Please help me explain. Thank you so much.
