Exporting Single Key/Frame Animations to .FBX not working. (Blender v2.76b)

Hello, I’m trying to export single frame animations to the .FBX format which doesn’t work, maybe I’m doing something wrong.

I’m trying to create multiple single-key animations using the action editor in Dope Sheet and export them to .FBX so I can use them in the Unreal Engine 4. The exported .fbx file has the mesh and armature (skeleton) but no animations, as if they where not exported. I checked this not only by trying to import them to the UE4, but also by checking the file in Autodesk’s FBX Converter tool.

The only way I can get the animations to appear is if I toggle the “All Actions” and the “Add Keyframe to beginning and End of animation settings”. This results in animations getting exported, but they then consist of 2 keyframes which is unwanted.

So my question is, how do I get single key animations into an FBX file,
Thanks for any help

I’m using Blender v2.76b and the Binary FBX Exporter v7.4 (also tried the ASCII version, same result)
