Book tracks not there

I posted earlier that Book CDs are not in order.  I just re-loaded everything doing one CD at a time, still not in order.   I also notice that Book CD #1 only has 10 of 17 tracks there?  I have copied CDs over in the past, always got a jumbled sequence.  I use Copy/Paste from PC to Clip Zip.  Never omitted tracks before?   Any suggestions?

No need for multiple threads.

Your ‘missing’ tracks are also an ID3 tag issue.
