It seems like you have many different meshes in the model you're exporting. Typically when you export a model, there will be a single mesh even though it may have physically separate parts. The crux of your problem being that animations work on a per mesh basis, so because you have 25 different meshes you're given 25 different animations. Take a look at this postlook at this post to join all your meshes into one. Hopefully it won't ruin your animation.
