Auto invoice creating multiple invoices instead of grouping all lines per grouping rules

Hello,

We observed that Auto invoice created multiple invoices for same customer, same invoice due date despite having grouping rules to consolidate them in a single invoice.

1) We had multiple streams with same stream element date.

2) Process Billable streams ran for almost 2 hours crossing the time over to next day.

3) This resulted into having records in okl_trx_ar_invoices_b with different transaction dates.

As a consequence, we have 2 different invoices with same due date.

Please suggest if this has been resolved as a part of any patch. We had ensured all attributes for grouping rules match for both lines.
