Thanks for the detailed explanation, looks like the selector logic is destroying the message distributin logic.
And one can assume that even if you have the selectors as the same
C1 ->"count > 0"
C2 ->"count > 0"
then only C1 (or C2) would be receiving all the messages. Could you please do a quick change and confirm this.
If the above is true then this is could be a bug, please create an issue in issue tracker.
