Character Rigging. Pose morph tag problem.


Good day!

When rigging, a somewhat strange problem arose…

It all started with the fact that I downloaded this rig.
Following the instructions after adjusting the weight, it is necessary to associate the poses of the face controllers and their animation via the pose-morph tag (in the video starts with 7:30).

Actually, it does not work for me. Video, where I try.

I wrote to the author of this rig and uploaded to him my file. The strangest thing for both of us is that he did not have such a problem in
my file. At it all turns out:

Tell me, please, what can I do wrong?
