[tor-relays] Bridge distribution method stuck at "none"

Hello. I tried to set up a bridge on an Ubuntu server and it seems working fine. I can connect to it manually from different devices using the bridge address from obfs4_bridgeline.txt file. However I dont see practically any traffic besides when I'm using it, and on "Relay Search" it shows as "Bridge distribution mechanism: None". The bridge has been up and running for 10 days straigth. At first I only had the line: "PublishServerDescriptor 1". After five days, I tried adding "BridgeRelay 1" and "BridgeDistribution moat", "https" and "any". Neither seems to have produced any change. Is this normal or could I have missed something on the configuration? Thank you.
