Traktor Pro Clock Uses All Sources...why?

I have just realized that my Traktor Pro is pulling the external midi clock from all midi ports and I can't find out where to select the source of the clock in Traktor.

In Controller-Manager the in-port and out-port have no effect on the midi clock (just for controller messages).

Anyone have any ideas?

P.s. If you are wondering why I have multiple clocks, I don't, I have multiple interfaces with the same clock. Because Traktor is using ALL the interfaces for the midi clock, it ends up doubling the actual tempo. Before we had the Controller-Manager, we could select the clock source by enabling and disabling certain interfaces in Midi Setup.

I just tried something...restarting Traktor fixed the issue.

So, this kind of sounds like a bug to me, like Traktor is not closing the midi port?

Here are the steps:

1) in Controller Manager, set in-port for the Generic Midi to "All Ports"
2) start sending some midi clock
3) at this point you should see your clock (Traktor in external clock mode)
4) in Controller Manager, set the in-port to none
5) you will still see your clock on traktor as being active

It should not be active at this point because you have no active midi inputs!

Can anyone verify?
