Qt6 Multimedia - Unable to Retrieve the "Title" of a Track

Kit: Android Qt 6.2.0 Clang armeabi-v7a

Video Source: https://bhaart.s3.ap-south-1.amazonaws.com/sri_ramachandra_kripalu.mkv

The goal is to parse the above video to list the audio track titles using MediaPlayer QML Type. 

The input video has got 6 audio tracks, each with a "Title" metadata.

The VLC Media Player correctly shows the titles (please see screenshot below).

I used the below code in QML to retrieve the TITLE metadata for each of the audio tracks. But it returns blank. 

onAudioTracksChanged: {
    console.log("onHasAudioChanged: ", audioTracks.length) //#tracks (PASS)
     //get audio track list
     audioTracks.forEach(function (audioTrack, index) {
         console.log("audioTrack1: ", audioTrack.stringValue(0)) //title (FAIL)
     });
 }

However, the LANGUAGE metadata is returned correctly

console.log("audioTrack1: ", audioTrack.stringValue(6)) //language

Can you please confirm this is a bug or if there are any workarounds?
