I fixed this problem by deleting the layout that was created with the possessions table was created. I recreated the layout and then the import worked properly. I did not modify the possessions table.
I with I knew what was wrong and why it started working.
I hope this can help someone else.
When you use Import Records from the file menu, you must navigate to a layout that is based on the table into which you want to import the records before you select this option.
