Copy and Paste Audio Attributes are not working as expected

I've run across an issue that popped up on the lastest version of PP that has me perplexed.  When I do the standard 'copy and paste' for audio attributers like I've done a million times beore, the audio effects copy, but the volume and keyframes do not copy (I have all the boxes checked in the attributes dialog box when I click on 'paste attributes'). 

Even stranger, if I uncheck the 'effects' box, the effects still copy to the segment.  

I have re-set my preferences, I have have re-set workspaces, I have created new projects and nothing makes a difference.  The volume and audio keyframes don't copy and  the effects copy whether I want them to or not. 

I've probably just clicked something somewhere that's created this problem, but I'm not seeing a solution anywhere.

Anyone have any thoughts as to what's going on?
