Logic changing sends to aux

Hi all. I have a patch that i have sent the kick and snare to a bus. That bus is then sidechaining a load of compressors in my track. About five I think. I just loaded an older version of the patch to check something out then reloaded the current patch that loaded with the project but the send was different. It still routed it the an aux track with the correct label. i.e drums sc

but has the actual bus was different I have had to go through all my compressors and reroute the sidechain.

Hope this is clear enough, any ideas. I also had Logic create two sends/busses with the same number?

Thanks. J.

That is exactly what I am after.

Awesome, thanks..
