Bone rotation gizmo displays as Global orientation when selecting multiple bones

Hi, I'm running into an issue when I try to rotate multiple bones along their local axis and I'm not sure if it's a bug or working as intended. See the following video:

As shown in the video, I can rotate the bones along their local X-Axis when I select them one at a time. But when I select multiple bones, the rotation gizmo seems to lock itself into the global orientation even though the editor UI still says Local.

I am pretty sure this is not an issue caused by the rig itself because I can rotate all of the finger bones along their local X-Axis in the Unity editor while NOT working on a UMotion Project, and the same is reflected in the Blender file.

Expected Behavior:

- Rotation gizmo should match the local rotation axis of the selected bones when they have the same orientation.

Extra Context:
- My model is setup as a Generic rig rather than a Humanoid.
