IK Armature timeline problem

Hi,
I started using the Bone tool in Flash CS6, and while doing the animation, the timeline of the armature broke apart (timeline number 1).

How can I combine the frames into one piece like in the timeline number 2?

btw - armature is the green timeline (not gray) what didn't work:
Trying copying pose and pasting in the other armature
Moving the frame to the place I want it to be (it just breaks the armature even more).
