Am I doing something wrong, or is this a bug?

I’m trying to edit my animation’s interpolation. So in the .gltf’s import settings, I went ahead and enabled the “Save to File” and “Keep Custom Tracks” options.

import settings

And yet, once I select any of the animations, I get the following warning:

This animation belongs to an imported scene, so changes to imported
tracks will not be saved.

To modify this animation, navigate to the scene’s Advanced Import
settings and select the animation. Some options, including looping,
are available here. To add custom tracks, enable “Save To File” and
“Keep Custom Tracks”.

the warning

Does anyone know how to get around this? I’d appreciate some help!
