Hello, I'm a student and very new to Maya. While trying to animate on my computer using the Graph Editor window, I always get some extra lines that don't make sense and aren't actually doing anything, they're not connected to any object or rig, and they're not editable or toggeable. I believe this may be a line display issue because the animations/file work correctly, it's just those lines that do nothing and are annoying. None of my teachers know why it happens and it only happens in my house PC, when I animate the same project in other computers the bug doesn't appear at all. I left pictures of how they look.
