Remove track image?

I can see how to add a new image for a track in the file edit options for the item - but no way to remove an image so that the track uses whatever my profile picture is.

Is there a way to do this please?

And if so, will the track always use my latest profile image, or will it copy whatever image was current at the time of removal and keep using that even if I later update my profile image?

I had this issue some time ago, support fixed this for me - I hope that they can help you too.
