Raspberry pi running Venus OS not updating firmware

I have a Raspi with a 64GB SD card running venus os v3.30. Under the online updates menu I see the official release of the large Image of Venus Os v3.54 available. I press to update, it starts updating, finishes the update, reboots, and instead of running the new version it continues with the old one. No warning of any type shown. How could this be? Any suggestions for firmware update?
