Adding armature with shift+e, but doesn't mirror in x-axis the file link
I want to add the armature that mirrors to the x-axis. But with mirror x-axis turned, press shift+e and armature turn to be strange.


If you know what happened, please tell me! Thanks!
Your armature object as some rotations.
In object mode, select the armature and press Ctrl+A / Rotation to apply it.
