Thanks for the replies!
Movie Set Id Check and refresh helped to populate total numbers for most sets, but not all. For instance, it still lists "3 of unknown" for "The Godfather Collection".
Also the incomplete movie set info filter still lists all of my movies in a collection whether complete or incomplete.
Finally, Missing Credits won't filter to those numbered movies even after several refreshes and restarts.
But don't worry too much. I can live without those new filters.

I'll have a look at these filters if AnotherPhil doesn't have time.
And the Missing Credits also.
