Hi Jonathan,
It is a relatively common question, I ask it all the time.
There are a few things you can try to do. Read all 4 before you make a decision.
1) Try turning your exit relay into a guard relay (ExitPolicy reject *:*). If no change after a week or so, it won't change. 2) Try resetting your onion keys by deleting everything in /var/lib/tor/keys 2.1) WARNING: Your relay is not new, looks almost 4 years old. When/if you reset your onion keys, you will get a brand new fingerprint, and you will appear as a brand new relay on the network, and have to go through all the stages again. That could be upsetting due to your longstanding participation, so be warned. Alternatively, save your onion keys somewhere safe, and create fresh onion keys to see if it works. If it doesn't work, put back your old keys. 3) Turn off your relay for at least a week. Let the network churn for a bit without you. It may help. 4) Do nothing. Ignore the previous 3 suggestions, and wait for more bwauths to be setup, which I've been repeatedly told are in the works and coming, and periodically remind people the problem still exists.
If you can, I would choose #4. If you are impatient like me, and also not horrendously fixated on your atlas stats, try any or all of the first 3.
