Reply to X-post - midi fighter deck assignment Q with S4 software?

I asked this in the TP2 thread and have searched around, but...... with TP2, S4 and a single midi controller: on the old traktor scratch pro, when the midifighter was assigned to deck A or B, the "A" or "B" in my window would be highlighted red.
With TP2, it's not, so I have NO idea which deck the midifighter is assigned to. I've tooled around, but it can't seem to work it, "A" and "B" are lit up blue on the screen all the time.

Anyone have a solution? Thanks!
