Yeah different vendors took their time updating the AGESA so it's possible it wasn't until July for your board.I'll check my BIOS when I get home. I think I should be running one newer than April. I'm pretty good about keeping it up to date, but there is a BIOS version for my MB from the end of July that I may not have installed. It includes an AGESA update.
This is the original video I made early 2017 to show the issue to EA.
