I have to say, it is not intuitive to me that Pretty Print would "clean" upon a switch from CV to BV. That's not something that I comprehended. After all, to my mind, that's not "open" or "save;" it's just a view switch. (Hmmm...I ponder, would it happen if you used the Preview from Code View? The PSO'D?).
I certainly have historically not set any type of auto-clean, but I see that in my latest upgrade to 0.7.1, it seems to be reset to auto-clean on open/save with PP. This certainly partly explains the issue, BUT....there's still something glitchy, because as I described, I never did have the opportunity to "manually clean" the missing tag. It was as I detailed, to the best of my recollection, and as it happened twice or so, I think I recall it reasonably well, given how many books have come since. ;-)
