Spent value does not update on entering time

User created time entries on a project, but the Spent percentage did not change in Projects > Structure screen on doing so.

This happens because the time you enter on the project is not approved yet. The % Spent and Spent fields in Projects > Structure screen track approved non-extra time and expenses of a project, not the unapproved ones. Check CORE Help Center for details on how BQE CORE calculates these fields.
