I found another error,  I have purchased the Emma Peel collection UPC="733961702491" howeverthe software will not allow me to edit the disc set and put the avengers 65 upc=733961700329 thru avengers disc set upc=733961700251 "nest".  Nor The software will not allow me to import / nest the discs for deep space nine  seasons 1 -2 3 5 6. It is a redundant error / glitch. the software cannot see the other discs when the selecting the discs to nest. 

The software would be improved with scan a group of movies to either read the upcs and the software look up the titles to create a list and/or mass edit for the list to adjust locations of movies

I ran the repair three times before contacting you and no it didn't fix anything.     Just ate time deleted unused cast the first time but not able to nest discs.  The software will not see the titles to nest product but is a catalog listing /report it sees them and the catalog itself sees them.  I am thinking of unloading product and restore catalog from a backup. To see if that fixes the problem.
