Redwood Sales Orders and lines Default data is blank

Summary:

Dear Experts,

We are observing a peculiar situation with Redwood OM page where none of the Sales order Information is available, either in Sales Order tab or Sales Order Lines tab.
The information gets shown (in Sales Order tab) only after doing some basic searches like drilling down to filters with 'Order number' or 'Creation date after' or BU etc etc.
But, this used to work fine earlier (to have all Sales Orders displaying in redwood for the BU that we have access by default) where there is no 'Saved Search' enabled, and used to show all existing orders.
