Orange clips in Timeline?

Hi All!
I poked around the forum and couldn't find anything about this already.
I recently began working with an editor. I transfer him the footage, and he has been sending me the .xml file back.
In the attached image you can see some of the clips in the timeline are orange, some are the normal blue. Why is this?
Also some clips remain black. I can see the clip # but if I "Show in Browser" it does not show me which segment of the clip is was. I've trashed preferences, render files, and restarted. It did not fix the problem. Still black.

Any help for either of these?

Check the assigned role for the orange clips. The blue is the default dialogue role.

By default that orange is a Music role, blue is Dialog, and teal (or whatever that's called) is Effects. He changed role assignments on you.
