Poses from pose library don't work when animating

I want to animate a human character and use poses for the pose of the hand that I already saved in the pose library of the character. When I am not animating, the poses from my pose library work just fine, but when I create keyframe-poses I can’t use any of the poses that are in the pose library of the armature. Nothing happens when I click on the apply symbol.
Has someone an idea how to solve this problem?

Thank you very much!

  1. In pose mode, select the bones that are affected by the pose.

  2. Apply the pose.

  3. Keyframe appropriate channels for the bones (loc/rot/scale.)


thank you very much!
