Solid Edge Unique frames appear as single item number in Reports

In this scenario, the user has a simple Solid Edge Frame assembly.

If they create a Report and use "Parts List"...

...and define Miter Cut 1 and 2 in the "Format..." the result is that the quantity is 3, whereas one of the components will be unique as it has a miter at each end.

By contrast, if a drawing is created of the Frame assembly and a Parts List defined, the components appear as two items.

How to display the correct number of Items in Reports?

In Solid Edge Options - Item Numbers turn on "Maintain Item Numbers".

The components will now appear correctly in Reports.
