Thank you lady and gentlemen for this advice.
It has made a big difference.
My main correction has been via the Reduce/Expand Key.
Now the backing IS in syncronisation.
I also take note of possible additional packages such as Style Set 17 and Real Tracks 33.

All these minor problems and setbacks are of course a good way to learn the program. Additionally , helpful individuals such as yourselves can also answer my mundane and naive questions..!! Again, thank you. (Till the next drama..!!)
