Only one animation is showing

By bulk export, I meant one click export all of the animations

引用自 Pte Jack：

Bulk Export animations for what format? What is it your exporting the animations for? FBX, Valve Model via Blender Source Tools, DAE...

Without knowing what you're trying to export for (ie game engine) then we can't really help.

I thought it was obvious that I wanted to export my anims with the Source tools because we're in the "Blender Source Tools" group

Is there a way to bulk export every animations (including the ones that are in NLA tracks) ?

Updating the addon from Github like Yagira suggested worked for me, thanks a lot.
