[tor-relays] Relay Bandwidth/Burst Change

I set torrc bandwidth/Burst to 5 MBs/6MBs respectively Then I get @7pm Local:  Received reload signal (hup). Reloading config and resetting internal state.  Read configuration file "/usr/share/tor/tor-service-defaults-torrc".  Read configuration file "/etc/tor/torrc".  After the above happens I'm back to Kb second.  If I understand correctly, torrc is the 'go to' default and  those settings [*should be*] used.  So why is the bandwidth/Burst being changed? Which  is REALLY annoying. There must be another setting  somewhere in Tor that I am missing?   Thank you for your help!
