Hello,
I've had this issue for a while and never bothered to explain it all out to try to fix it. I have a custom view setup that drives something like this:
Artist > Tour > Date > Recording Source > Type (16 bit/ 24 bit) > Tracks.
I have the same view setup for Theatre View and it works just fine, but in the standard view, it doesn't show the Source part as I think it should. The first three levels work great and they're based off of library fields. The 4th and 5th levels are RegEx fields:
Source: regex([Filename (path)], /#\d{4}-\d{2}-\d{2}\.(.+?)\.flac\d+#/, 1)
Type: removeright(ListItem([Filename (path)],math(listCount([filename (path)],.)-1),.),1)
I've attached screenshots of what I see at the different levels. When I get to that Source level, it displays the Artist Name, not the RegEx that I've built. In Theatre View, it shows the source as I expect. Am I missing something? Thanks!
