[tor-relays] Bridges and advertised bandwidth

Hi everyone. I am currently operating 4 bridges on VPSs. They all appear to working correctly. However, 2 of the 4 bridges have 0kb/s as their advertised bandwidth while the other two are advertising around 100KB/s. Is there a reason for the 0kb/s? Does this indicate an error in my bridges or simply a gitch? See this for reference. https://globe.torproject.org/#/search/query=acrossthebridge Thank you.
