Poly Config Overbridge BUG

Hi,

I use my Analog 4 as a four input audio device in my DAW to record the four track at the same time with overbridge enabled.

When some of my track are in poly mode, i hear the sound of other track in some tracks ???

For example if i set poly mode like this O X X X

i will hear the sound of the track 2 in the track 4!!!

Really strange bug!

No one else have this problem ?
