Some Imported Files Cracking and Popping

As a little bump to this, my previous imported project had about 50 tracks.  As I listened back to all the tracks for the first time, I noticed that the bass track waveform was clipped for about the last half of the song.  Same thing for a drum loop.  I figured there was a recording glitch.  When I looked at the waveforms in Adobe Audition, they looked fine beginning to end.  These tracks also had the same intermittent popping and clicking I mentioned above.  I have the most recent drivers and my samples are set to 1024.  CPU usage across all my cores does not go about 50%
 
Here's another curiosity.  The second song I observed the popping and clicking with, some of the imported waveforms have tiny blips in them.  On the first version of song, these are the tracks that popped and clicked.  I created another project, imported the clips individually, and the tiny blips are in the waveform, but no pops or clicks in the audio.  If I freeze the track, the blips go away.
 
In looking at some of the other posts where Windows 10 updates may be a related issue, I have just started using CA-2A in the ProChannel just about one week ago.  Not sure if that's related or not.
 
Again, any thoughts would be appreciated.
 
Thanks!
