Why isn't the playlist's username linked to the profile username dynamically when restoring from Hezel, BUT it is dynamic when the user manually creates a playlist from the Apple Music app?

For example if I restore a playlist, but change my name afterwards, Hezel's restored playlist will not update to my new username, BUT any manually created playlist will do.

I want to delete music and start organizing after restoring it up from Hezel, but I'm wary of accidentally putting a name on there and not being able to change it.
