V11 datatable reports not working properly

Facing issues in filtering with partial loading of data for most reports using datatables after updating to v11.
For example, ‘sales orders to be delivered’ filtered for a item showed total as 10 but on refreshing went on to 395.
Script reports and filters work fine though, so I believe it is to do with datatables only.

Wondering if this is being encountered by everyone?

Anyone?
