Firewalla Gold Pro not releasing old ISP IPv6 addresses.

I changed from Ting Fiber to Quantum Fiber and I can't get a new IPv6 address. I have turned it off and back on and even turned off the power to the whole network and back on again and no change. I put on a TP-Link router and I get a new prefix and everything works fine. Turn it all back to firewalla and nothing but the Ting address. When I look at the lease info it is all blank.
