Problems Changing Album Art

[Bosh]

Have been using TwonkyServer on a QNAP TS210 for a couple of months and ripped 800+ CDs to FLAC for streaming to my Naim Uniti using Naim's Iphone control app

On some early rips of obscure discs I assigned a "provisional" album cover assuming I could replace that "folder" jpeg with the correct one. Wrong. Now no matter what I do, clearing Caches on iPhone, deleting cover, deleting all relevant files, re-ripping, changing artist name, I cannot get rid of the "provisional" cover

Any idea of how to do this?

Thanks

Ideas:

1. Try rebuilding the database on the server settings pages.
2. Make sure your files don't have embedded album art.
