Problem with cast in Plex if two people have the same 'role' (documentary)



The documentary 20 Feet From Stardom has a cast of 18 in 12 have the role ‘Herself’ and 6 have the role ‘Himself’.

When the metadata has been loaded into Plex, only the first ‘Herself’ (Darlene Love) and the first ‘Himself’ (Mick Jagger) are displayed.

It looks like Plex isn’t allowing more than one actor for the same role; but this doesn’t work very well for documentaries. Can this issue be fixed?

I’m currently on PMS version, but I have occasionally noticed this issue before.
