Assigning a Buss

After assigning a channel to a buss, and panning that channel and the result doesn't show up in the buss, it comes out summed.  If I pan the buss, it pans fine. 

If I have a lead vocal and want to group my harmonies to a buss, panning them each to thier own spot, it doesn't work - sometimes.  I have session files where it works fine and some that don't and I can't seem to find a difference.  Tonight after fighting with it for an hour, I sent the output of the channel to a stereo out on my motu instead of a mono out.  After that, I could send it to the buss and panning worked fine.  Am I missing something here?  Or have other been having this problem.  Or am I just confusing?

Any thoughts?  It drive me nuts

Did you have any effects on the bus?  If so, which ones?  I believe I came across this myself, but only when using certain effects on a bus.  Although, it's been so long ago that I don't remember which ones.

No - no effects but I seemed to remember having to try that, or at least stumble onto it.  If assigning the output to a stereo pair does the trick, I'm okay with it but it is strange.  It definitely makes me wig out
