The External Instrument's audio is coming up on another channel?

OK,

I have a MOTU 128 MIDI interface and MOTU 828 mk3 audio interface.

I have checked numerous times that my 3 keyboards are routed correctly.

...all the MIDI ins/outs are correct and the keyboards audio routed to the mk3 is correct.

Now, in Logic I want to use each keyboard as an external instrument (EI).

When I create a new (EI) lets says my Alesis micron, its input is 1-2.

Next (EI), Juno-D. Its channel is 3-4.

If I play something and make a little loop on the Alesis' channel I can hear what I did...so thats good.

But if I mute that track (the Alesis), I still can hear what I just recorded.

Well,..the audio is coming in on the Juno-d's channel 3-4.

Its the same for when I create my next (EI). The motif. Its channel is 5-6.

If I play something from the Juno-d, record and loop. I can hear it...but if I mute Juno-d's channel, its coming in on Motifs 5-6.

Something in Logic is routing an EI instrument into the next ascending channel

Whats wrong?

Thanks
