Apple Logic Pro /LogicExpress Discussion

Actually, I can delete objects, but when I try to delete unused busses or outputs, I get a message saying that whatever I'm about to delete is "assigned to a track in the arrange window."  I think Logic is lying to me.  

Most recent:  Bus 3 has a delay insert.  No audio objects are sending to this bus, I have no tracks assigned to this bus, and when I ignore the dire warning and delete it, nothing visible happens in the arrange window or track mixer.   

I'm happy to click "Delete Anyway", but am too compulsive to do so without checking every track and audio object to make sure I didn't miss something, and I never did, so there's a big waste of time involved every time I try to delete some random unused audio object.

 Is this a bug, or is there some other place where assignments are made that I can't see?

Thanks for anyone's input.
