When I first started tagging my music collection, most of the performer role tags was lowercase, example:
Performer: Steven Tyler (guitar)
I've since then changed it to uppercase:
Performer: Steven Tyler (Guitar)
The issue I'm having is that when I start to type a role in "Multiple Artist Splitter", the drop down menu presents me with a mix of lowercase and uppercase roles, but there's never any duplicates, like this:
Even if I begin by typing the role in uppercase like "Gui", it still presents me with a lowercase alternative.
I've run an mp3tag action on all my files to make sure they're consistent (begins with uppercase). If I search and replace all tag fields in MB for "guitar" and select "match case", no results show up. How come it's still in the drop down menu if there isn't any tag like that in my files?
Edit: When I say "uppercase" I mean that the first letter of the word is uppercase, not the whole word, just to clarify.
