Invoice no longer displays amount paid/due
It appears the PDF invoice no longer displays the amount paid or due. I'm not sure if this is a regression in 5.29.0 or earlier, but it definitely is in a recent release.
To reproduce, enable invoicing (Administer > CiviContribute > CiviContribute Component Settings), view an completed contribution and generate an invoice. It previously would include the amount paid and balance due. See screenshot sample.
