Mc.wave~ playing identical channels?

Hi all, this seems like a bug, as I didn’t find anything pointing out it’s an expected behavior:

I have a buffer~ with 8 different channels, and I’m sending a single ramp (0-1) via mc.dup~ 8 to mc.wave~ @chans 8.

However, as output, which is sent to mc.daw @chans8 there are 8 identical channels - they all are playing the first channel in the buffer.

(Yes, I need to use mc.wave~ for the task)

Any ideas?
