I am freezing some tracks from EastWest PLAY instruments. Most of the tracks froze just fine. A couple, however, do one of two strange things:
 
Strange Thing 1) At the end of the piece, when the freeze is supposed to be done (I'm not using fast bounce), instead of turning the midi into an audio track like it's supposed to, it starts over. If I Esc out of the process, it asks if I want to keep the partially rendered audio like it would had it not already just gone through the whole song already. If I say Yes, to keep partially rendered audio, it starts freezing from the beginning all over again. If I say No, it goes back to Midi. I thought maybe it just wants to go through twice for some reason, but no, it will continue to loop through the song over and over until I Esc out.
 
Strange Thing 2) After going through the freeze process, the track completely disappears, though it plays back normally as if it were there. I go to Track Manager and see that the track is unchecked, so I re-check it. It appears again, but is Midi, not audio. Also, if I solo the track folder this track is in but then UN-solo the track in question, I still hear the audio, as if there is another phantom audio track there. I tried un-checking Hide MIDI track from freeze options and trying again. This time the MIDI track stays there, but there is no audio track anywhere. And yes, I scrolled to the bottom to see if the track somehow just got moved to the bottom. It's nowhere to be found.
 
For both of these problems, I've attempted to fix them by creating brand new EastWest synths and dragging the Midi clips to the new track and trying again with the new track. No difference. And as I mentioned, most EastWest tracks have frozen just fine.
 
What's going on here?

The only thing that comes to mind is for problem 1 are you using MIDI loops? 
 
For problem 2 is it possible it isn't freezing at all?  
 
I haven't seen this kind of behavior with my freezes. I don't have East West though.

Not Midi loops. I have frozen tracks before while a loop was inadvertently left on, and the freezing process ignores the  loops.
 
For #2, yes, it's possible it isn't freezing at all, but the Midi track shows the freeze button highlighted as if it were.

More information on problem 2 above: After freezing the track and seeing the original Midi track still there, but with the freeze button highlighted, I went in and edited the Midi, adding and removing some notes, and on playback the changes were not played. Clearly, the track is frozen, and is playing back the resulting audio, but I am seeing the Midi information in the clips instead of audio. Because Sonar thinks this is still a Midi track, I am unable to add effects the way I could if it were an audio track. If it were merely a visual problem, I could live with it. But it appears that I have a frozen track here playing back audio, I just can't see it or work with it as audio. Frustrating. Maybe I'll just record the track to a separate audio track the old-fashioned way.

I have no more ideas. I would contact Cakewalk.

A couple of thoughts which may or may not help.
 
Before freezing, select the entire Midi track and bounce to clip
 
Secondly, if you're hearing audio after freezing the audio track MUST be there somewhere.
Do a Shift + H to display all tracks and identify what each of them are doing
