not all custom mp3 tags are shown?

[Cableguy]

I have this problem too. I edit all my tags in mp3tag. Some of my custom tags applied to mp3's don't appear when browsing certain indextags. Those files have only one tag though, so no issues with separators.
For example, all files in my library appear when browsing by artist, but when browsing by artistsort, the mp3 albums get excluded. The same goes for my custom tag label.
