Audio track name not set when using AC3 Passthru

Problem Description
Audio track name is not set when using AC3 Passthru.
"Name": "..." setting is not appearing for the second audio track in the provided log file but I do confirm that I manually filled-in the "Track name" field.
The workaround if found is to use the following command on the output file once the encoding process is complete :
MP4Box -udta <#>:type=name -udta <#>:type=name:str="My track name" HBEncFile.mp4
<#> --> to be replaced with track ID hereabove
Could be nice if you could fix or integrate the workaround in your process.
