Audio files are blue and green and will not 'Auto match'

Two questions here:

1) I have what seems to be a common issue with mixed results. Most of my audio files will not auto match loudness. They are all tagged as dialogue, but give the error icons and say 'some of the seleceted clips are enabled while others are not' and 'not all selected clips have the same control value...' I have tried this with the entire timeline (~3 min), chunks of the timeline, and two files alone. It always gives the same error. 

2) Most of my audio files (that are linked to a video) are green, but a few of them (VO sent separately) are blue. I've looked in my labels tab in preferences and nothing is labeled as blue. Any idea what that's about?

Thanks in advance. It's getting better but man, trying to learn this thing has been a bear.
