CG50 Report Management - Report Additional info doesn't show number of pages

Hi,

In Report Management (CG50), the reports created used to have a number in Size in Pages field in the Additional Information screen (click on blue I icon), but for some reasons, the reports generated recently shows '0' in Size in Pages field, eventhough Size in bytes field contains a value (for example: 449462).

Please advice why this is happenning and how to fix it?

Thanks,

David
