Problems with exporting animation

Hi. I need some help with the Action Editor and the Animations Tracks. I’m not very sure about a lot of things about the Action Editor and the Dope Sheet in Blender, as I’m very new doing animations in Blender, so I’m sorry if all of this sound a little confusing and confused.

I have two characters. I’m working with them for a webcomic, and I want to simulate the clothing in Marvelous Designer (I’m a total noob with the cloth simulation in blender). So, I have two separate .blend files for the characters (Ellen and Riley), and the general .blend file with all the things. I did the poses for the characters in the general file, one Pose Library for each character. Later, I append the appropiate Pose Library in the .blend file for each character. With Ellen I could export all the poses in separated .fbx files without problems. But with Riley I have a huge problem. Blender seems to export the Animation Track with all the poses, not the new Animation track where I only have the A Pose and the final pose. I didn’t change nothing between the to files, and I don’t know how to get Blender to export only the poses that I need.

So, is there some solution? Because I can do it in a different way, but it will took longer, and I want to know if there is some solution for this, as I think it will be necessary if I want to do some animation more complex.

Thank you very much!
