Hi,
After searching in the forum I could not find a suitable reply to the following problem
I reassigned collection numbers by title for the umpteenth time, only to discover that some gaps appeared in the collection list numbers, but only in reference to some 'child' titles.
Tried to edit these titles and found that they had been assigned a number already assigned to another child title in that same box; then tried to manually assign the correct number but it didn't work, the gap was still there.
Then another strange thing happened: in order to solve the problem I logged in in order to download the previous collection from the database, but according to the software my collection was made of 4000 or more titles, whereas I own approx. 1600.
Help!!!!!!
What's happening?

Try a partial reassignment with all checkboxes set except for "None" (unless you want to get rid of those too).
