Regarding your Credits mappings from your last posted config file:
Credits: Producer:Producer, Composer:ignore, Artwork:Artwork, Photo.*:Artwork, Engineer:Engineer, Assistant Engineer:Engineer, Coordination:ignore, Art Direction:Artwork, Mixing.*:Mixing, Mastering.*:Engineer, Live Technician:Engineer, Live Sound Engineer:Engineer, Design:Artwork, Digital.*:Engineer, Member of Attributed Artist:ignore, Remaster.*:Engineer, Liner Notes:ignore, Original Photography:Artwork, Primary Artist:ignore, Cover.*:Artwork, Illust.*:Artwork, Pre-Production:Engineer, Equip.*:Ignore, Audio.*:Engineer, Manage.*:ignore, Group Member:ignore, Unknown.*:ignore, Special Ass.*:ignore, Drawing:Artwork, Original.*:ignore, Sleeve.*:Artwork, Memor.*:ignore, Retouch.*:ignore, Pre-Produc.*:ignore, Songwriter:ignore, Project.*:ignore, Assistant Producer:Producer, Executive Producer:Producer, Remix.*:Mixer, Compilation Producer:Producer, Produc.*:Producer, Assistant:ignore, Vocal Engineer:Engineer, Pro-Tools:ignore, Additional Pers.*:ignore, Editing:ignore, String Engineer:ignore
There were a couple of problems:
1. the word "ignore" must be in lowercase - you had one as "Ignore". This is just to help make it clear it is not an MC field.
2. You have Pre-Production:Engineer and later Pre-Produc.*:ignore. It just happens that the code uses a first-wins implementation, so Pre-Production would be mapped to Engineer, and not ignore. If that's what you intended, it works.
Since the left-hand side of the mappings are regular expressions, you can make the credits shorter by using the OR | character, and broken down, you basically have these 5 credit groupings (ignore, Artwork, Engineer, Mixer and Producer):
(Additional Pers.*|Assistant|Composer|Coordination|Editing|Equip.*|Group Member|Liner Notes|Manage.*|Member of Attributed Artist|Memor.*|Original.*|Primary Artist|Pro-Tools|Project.*|Retouch.*|Songwriter|Special Ass.*|String Engineer|Unknown.*):ignore
(Art Direction|Artwork|Cover.*|Design|Drawing|Illust.*|.*Photo.*|Sleeve.*):Artwork
(.*Engineer|Audio.*|Digital.*|Live Technician|Mastering.*|Pre-Production|Remaster.*):Engineer
(Remix.*|Mixing.*):Mixer
[^-]*Produc.*:Producer
These can now be combined for a shorter and grouped by mapping final Credits line in the config file :
Credits: (Additional Pers.*|Assistant|Composer|Coordination|Editing|Equip.*|Group Member|Liner Notes|Manage.*|Member of Attributed Artist|Memor.*|Original.*|Primary Artist|Pro-Tools|Project.*|Retouch.*|Songwriter|Special Ass.*|String Engineer|Unknown.*):ignore,(Art Direction|Artwork|Cover.*|Design|Drawing|Illust.*|.*Photo.*|Sleeve.*):Artwork,(.*Engineer|Audio.*|Digital.*|Live Technician|Mastering.*|Pre-Production|Remaster.*):Engineer,(Remix.*|Mixing.*):Mixer,[^-]*Produc.*:Producer
or the easier to read multiple Credits line version:
Credits: (Additional Pers.*|Assistant|Composer|Coordination|Editing|Equip.*|Group Member|Liner Notes|Manage.*|Member of Attributed Artist|Memor.*|Original.*|Primary Artist|Pro-Tools|Project.*|Retouch.*|Songwriter|Special Ass.*|String Engineer|Unknown.*):ignore
Credits: (Art Direction|Artwork|Cover.*|Design|Drawing|Illust.*|.*Photo.*|Sleeve.*):Artwork
Credits: (.*Engineer|Audio.*|Digital.*|Live Technician|Mastering.*|Pre-Production|Remaster.*):Engineer
Credits: (Remix.*|Mixing.*):Mixer
Credits: [^-]*Produc.*:Producer
Note: in the next release, I've reversed the MC field/regular expression, so lines will look like this:
Credits: ignore:(Additional Pers.*|Assistant|Composer|Coordination|Editing|Equip.*|Group Member|Liner Notes|Manage.*|Member of Attributed Artist|Memor.*|Original.*|Primary Artist|Pro-Tools|Project.*|Retouch.*|Songwriter|Special Ass.*|String Engineer|Unknown.*)
Credits: Engineer:(.*Engineer|Audio.*|Digital.*|Live Technician|Mastering.*|Pre-Production|Remaster.*)
