The duration of a Scheduled Offering is not what is configured within an Item.
SAP SuccessFactors Learning Management System (LMS) - All Supported Versions
Reproducing the Issue
The length configured within the Item is 8 hours
The length of the Scheduled Offering is, in this case, 7 hrs 27mins
Within the Item, the Segments section has been populated. Within here the length of the Item's segment is defaulted to 7.45 thus overriding the length specified in the Item itself.
You can leave the values as they are or update the value in the Segments tab to reflect what is populated in the Item itself.
