Hi Joshai,

These tables are automatically created and managed by Fabric Plan for each sheet and act as the application's backend storage.

The tables are used to store:

1. Data input values entered through writeback
2. Comments and annotations
3. Writeback configuration and settings
4. Payload and collaboration metadata
5. Other internal logs required for planning and multi-user collaboration

It is normal for some of these tables to appear empty, particularly if no writeback data, comments, or collaboration activity has been recorded yet. Fabric Plan automatically creates and manages these tables as part of its backend infrastructure for writeback and collaboration features. Since they are system-generated tables, they should not be modified or removed.

Hope this helps!
