Multiple artist on music videos

[lanos 4]

I'm going through and editing organizing my music/music video meta data and I cant seem to save multiple artist on the editor when dealing with music videos. Say I have Lonely Island featuring Timberlake, under the artist section on the editor I put "Lonely Island;Justin Timberlake" hit save but only Lonely Island saves and the Timberlake part is just deleted

Did anyone end up finding a fix for this as im having the same issue and have no idea how to add 2 artists to the music video.
