Wavelab speaker configuration not working?

I have configured 3 speaker configuration, but if I select SPC 2 or 3 in the Master Section then it still plays through SPC 1. I have seen an earlier post about this for WL 10 (WL Pro 10.0.50 - Speaker Configuration) but it is unclear to me if this issue was ever solved.
