MinimServer not finding Publisher tag in FLAC files

[edj]

Hi there. I've only been using MinimServer for a few weeks (on a Synology NAS) and am really liking it. I was put onto it by my Dad who has been using it (and singing its praises!) for ages...

Anyway, the Publisher/Label is quite an important tag for a lot of my music so I wanted to have it on the initial index; mine is pretty simple: Artist:Album Artist, Date, Genre, Label:Publisher

I have tried messing around with the last part - just Label, just Publisher, merge, etc etc - but whatever I try, MinimServer doesn't seem to want to find/index the Publisher tag for any FLAC files. It works for MP3s fine (my collection is just FLAC and MP3).

If I select Publisher from the main Index, the only Publishers showing are ones associated with MP3 files. If I choose a Publisher that I know has both MP3s and FLACs associated with it, only the MP3s show.

I have tagged/organised all of my music using Mediamonkey and verified with MP3tag that the PUBLISHER tag is used correctly with both MP3 and FLAC files.

Any idea why MinimServer isn't indexing the Publisher field for FLACs? I have looked a little deeper into the settings/help guides and can't see anything relating to this.

Any and all advice appreciated... Cheers - Ed
