I have had MP3tag options set per attached screenshot for years, so that when saved the ID3v1 tags are removed. This has worked fine for ages. Recently however I have noticed it is no longer working - I am not sure which version this started from though. As you can see the ID3v1 tags remain even after I have made a change to a track and resaved it. Previously they just disappeared.
Has there been a change in this functionality recently?
