ListItem.FolderPath Question

Hi, I use $INFO[ListItem.FolderPath] to show albums of artists of my library in the right bottom, like this :

I want to use the same to show albums in artist dialog info but in this window it show all items inside artist folder (artworks files and extrafanarts folder) :

There is a way to hide this items or another solution to show only albums in my library for selected artist ?
