Batch print checks only prints the first check

Cannot find anyone else submitting this issue, so it must be our instance. But I am scratching my head.

TRANSACTIONS>PAYABLES>PAY BILLS

Select the bank account

Check the TO BE PRINTED box

Select 5 bills, all different vendors & click SAVE. Process completes with 0 Errors and lists the 5 checks as TO BE PRINTED.

TRANSACTIONS>MANAGEMENT>PRINT CHECKS AND FORMS>CHECKS

Select an ACCOUNT, enter the FIRST CHECK NUMBER, choose a CHECK TYPE the click PRINT

One new tab opens but only the first check appears in the tab. HOWEVER, NetSuite marks the remaining 4 checks as printed.

Have tried the same sequence with printing multiple batch INVOICES and they print as expected.
