P0011 Batch Control does not display header info

Several AP users have experienced the following:

From Supplier Ledger row exit or directly in P0011 Voucher Journal Review-Batch Approval, users receive no Batch Header information for batches in which they normally expect; i.e. there is blank information in data fields on the screen.

We've looked at F0024 Batch Approvers permissions for some of these users, but are not certain that this is the reason for the issue; we don't think Approvers permissions have changed. No ESUs or custom modifications have been deployed.
