Paste Attributes Broken/Not Working/Bug

Running 10.1.1 on Mac Pro 4,1 GTX680, RAID0, 48gb RAM, blah blah blah

For some reason, many of my clips in a certain project have lost the ability to copy and paste attributes. If I bring a fresh clip onto the timeline, I can copy/paste attributes to another fresh clip. If I bring in a "clean" version of a clip from the browser that's already on the timeline, I can copy/paste attributes.

I think this bug has to do with audio effects that have been placed on the clip (Compressor/Fat Eq etc.) but I haven't been able to narrow it down.

I've seen this complained about before on earlier versions of FCPX, and I experienced it once before and it went away, so I'm trying to get to the bottom of it. Anyone else have experience with this?

If this only happens to clips in a particular Project: create a new Project and copy/paste the clips of the problematic Project into the new Project timeline.

I've recently had the same issue and first noticed it when trying to paste loudness and levels between items.

Did this happen on an older project that was updated to 10.1, or on a completely new 10.1 project?

This behavior is happening on a project that was updated from 10.09. Copying the clips into a new project makes no difference. I've tried resetting prefs, deleting render files, and resetting those clips to native settings in another part of the timeline. This is happening on ProRes footage with minimal effects or none at all. Very odd...
