Exporting animations problem with prefix "Armature"

Hello guys! I need a hand.
I’m working on an update for a game that was developed 3 years ago. At that time I wasn’t on the project. Now, they want to add characters and for them to use the same animations. The animations were made in blender, which I don’t use, but I was able to learn to rigg in blender and reuse them. There are no issues there. Now, MY PROBLEM is that when I export the fbx file, the animations get renamed with the prefix "Armature | " How Can I get rid of that?
Thanks in advance.
