lines in TSCN file get duplicated

Godot Version

4.2.2 C# Version

Question

Hey, I am not sure why this is happening, but I am trying to make my animations unique in the animation player so i can make a certain animation loop without changing the import (i know i should just change the import but thats besides the point), but when i make it unique, it for some reason adds all of the animations to the tscn file multiple times which turns it from a 200 lineish tscn file to 50000 lines, and when i tried to manually delete the extra lines, godot now cannot open my tscn file. Does anybody know why this duplication happened or what i can do to prevent it in the future? This has also happened to my partner with changing transform values and neither of us are sure why.

You trying make unique with csharp ? show your code.

oh no sorry not in code, im making unique in the GUI, but its the csharp version of godot, thought maybe that would be helpful to know. I am doing this all in the engine GUI when i am trying to work with my animation player and animation tree for my character
