I found this that explains the problems I have.
Now my goal is to find really animaciuones full perm. Those who had bought in theory and they were.
Why can't I use an animation or sound in a gesture?In other words, why doesn't an animation or sound appear in the dropdown list when you're editing a gesture?Check if it has full permissions. Animations and sounds must have full permissions to be included in a gesture. This is because a gesture functions like a "wrapper" that references individual animations and sounds. If an animation was no-transfer but the gesture could include it, that'd be an unfair way to work around the creator's permissions. A similar case applies for non-copyable animations and sounds.It's true you can't do much to modify animations and sounds after uploading them aside from renaming and changing their description, but the rule still holds true
