Prefix Delegation Disabled

Is anyone else having issues with their delegated IPv6 prefix? Our CGA4332COM correctly shows our assigned /56 address but it is not handing out the /59 prefix to our router-firewall. This seems to have started this week so I suspect this is caused by a recent firmware update. Tier 1 support refused to assign us a ticket and refused to escalate. They were going to send a tech on-site but charge us for the service since their monitors all show green. I could not convince them that this is not a line or hardware issue. Until this is resolved, my servers are unreachable on their IPv6 addresses.

Wireshark shows the following DHCPv6 response (emphasis mine) which makes me think this was through an update. If that is the case, we can't be the only ones having this problem.
