Blender only exports the current animation

I ran into a problem with blender wich i never seen before. I’m using blender for a long time ago. The problem is, when I export a character with multiple animation, only exports the last edited animation.

The problem comes when i added a new action to the animations. All animations are tagged with this F thingy. It can be a simple failure, or I just accidentally pressed a button.

Oh, i got the solution. I accidentally pressed the push down button in blender. So the action was added to the NLA editor. Unity doesn’t suppors NLA editor. So I loaded an autosave and it’s everything good now.
