Data is not showing when it is Refreshed - Hybrid Mode EPBCS

Hello, We are trying to implement the hybrid mode in production but during testing in our spare environment, we tried to delete or configure data and submit it through SmartView in Excel. Afterwards, we "refresh" it but then the original data isn't showing.

As the Hybrid Mode is already aggregated, my understanding is, despite the configuration, it will still pull the original data when it is refresh without having to trigger the aggregation script it is connected to.

Any insights? Or explanation to further understand the hybrid mode enablement in EPBCS especially the aggregated cubes.

Thank you.
