Not sure if this is a problem, so it's not a support ticket.
I have a long list of Songs, which includes some Smart Copies. There is also a Tag, called SC, which I tick for Smart Copies. I like to see in a Setlist if a song is a Smart Copy or not. Is that important? Maybe.
On displaying that list of songs on PC, I chose that SC Tag to filter by, expecting to see all my Smart Copies of songs. I got none.
Should I expect that behaviour? I'm not sure.
"Hide Smart Copies" is not selected and of course they appear until I choose that SC Tag.
