We migrated a site from SP 2007 to SP 2013.  A list in the site (newlist1) had a problem in that the import did not bring the most current version of all list items.  Rather than try to figure out a solution to that problem, we created a new list (newlist2) and ran the import again from SP 2007.  This time, when we create a new list item in newlist2 it creates fine, but when we edit it pulls up a list ID from newlist1(they have the same ID)! This list item doesn't even exist in the old SP list.  How can this be? How can one list pull the data from another list? We are at wits end to get this list up and ru
