Interactive/Live Avatar not Showing Hand Movements

I recently trained and deployed a Custom Avatar using Azure Speech Studio. I had trained the avatar using videos in which there was significant hand movements.
To test the avatar, I first checked it in the Text To Speech Avatar section where I gave a script as input and the generated a video of my custom avatar reciting that script; showing hand movements as well. This worked perfectly.

Now, when I tried to test it for Live/Interactive Avatar, I noticed that the avatar showed no hand movements at all, as opposed to the same avatar being used in Text To Speech Avatar section showing significant hand movements.
The avatar would be standing straight and rigid, with no movement except the slight lip movement it performed trying to lip sync. Even the lip sync was not as good as compared to the Text to Speech Section -Script Based Avatar.
I even tried the same test out with prebuilt avatars provided by azure- Lisa, Harry.
But even they should the same results, where they would be standing perfectly still and would not be displaying any movement.

To further test it, I even tried to set up a custom UI where I would call the avatar and set the "amplitude" parameter (responsible for determining how much movement the avatar will display) to the maximum value (1) but still I observed no change.

Why is there no hand movements being displayed?
The same avatars being used in Text to Speech Section (Script Based Avatars) display proper hand movements.
The custom avatar was even trained on videos which had significant hand movements.
How to enable these hand movements in Interactive/Live avatar?

Just to be clear, I am not talking about gestures here, but rather hand movements which the avatar automatically performs without the user having to manually insert them.
