How to 'see' the vocals in Rekordbox 6.01?

Hello! I have RB 6.01 up and running. I already analysed some tracks with the vocals turned on. But I don't see the vocals in the waveforms? I choosed all kinds of waveforms but I can not detect the new feature to see the vocals?

Does someone know how to see them?

Thank you!
