In configuration, for the inspection point identifier at the bottom of the screen is a field:
"No. insp. points for char. summariz."
Make sure that has a number larger than the number of inspection points you expect.
Below that is a check box. "Last inspected sample is valid". Make sure this is NOT checked.
I suggest you read the help file available for each of these fields.
Lastly, make sure each of your inspection points is valuated and closed.
