[tor-relays] Bridges not being distributed

Hello, I notice (almost) all bridges are showing their distributor mechanism as None on Tor Metrics.[1] There are also hardly any in the latest pool assignments file from CollecTor.[2] Curious as to why? Is this a change that needs fixing on a bridge operators end, or simply BridgeDB not reporting properly?
