Every time I open style picker this style is the first one on the list despite the fact that it doesn't exist. I know it doesn't exist because I removed it myself, as after listening to it I know I will NEVER use it. Not my style of music. Yet there it is.
It's called !byrddu3.sty. My Real Band seems to want to default to this style.
Note it says [NA] because it doesn't exist. So doesn't that make you want to ask, how can RB find a style that doesn't exist, list it, AND THEN tell me it doesn't exist?
In this example, the search criteria was funk. There's no reference at all to funk on that line or in that style.
