Colon prefix when using tagvalue

[RoyMussell]

Hi, I couldn't find an answer to this in the forum but I must be missing something.

My MP3s have an Artist tag for sorting e.g. 'Adams, Bryan' or 'View, The' and a Comment tag for displaying e.g. 'Bryan Adams' or 'The View'. (For historical reasons, it seems to be very difficult for me to use the ArtistSort tag.)

I am using itemTags = Comment and tagvalue = Artist.value.index.display={Comment}. Everything works brilliantly except that the Artist is always prefixed with a colon e.g. ':Bryan Adams'. Is this by design or am I doing something foolish? Can I get rid of it?

Your software is brilliant by the way. Thank-you so much for all your efforts.
