Not all Animations when exporting to FBX

I am trying to export an Armature Model with 7 Animations in the FBX 7.4 binary format. But when i Import the FBX file back to blender, it has only 4 Animations. I am using the normal Export Settings, i have not changed the default export Settings. I am using Blender 2.73. Has anyone an idea why this is happening?
