Can you send us a link to your relay on Relay Search, and a copy of your torrc?
It's hard to debug without detailed information.
I already filled a ticket and included my torrc there like requested from nick: https://trac.torproject.org/projects/tor/ticket/32541
Yesterday i checked the MyFamily line on all relays so that it now is definitely the same on all relays which are part of my family because i stopped caring about the MyFamily option weeks ago after it seemed to not work like expected. Then i sent a HUP on all relays and waited for metrics to show them like expected so that all 23 relays are shown as "Effective Family Members" on all relays and that no relay is listed as "Alleged Family Member" now. About two hours later the changes were shown that way in metrics.
Then i commented out the MyFamily line on angeltest8 7AAF5597B18D82CC90CA95FB7976A1CEA4A32E06
and sent a HUP on that relay again.
Four hours later still nothing changed in metrics so i stopped and started the tor daemon to be sure that the commented out MyFamily line is definitely recognized but today still no change in metrics and angeltest8 is handled like before.
But as far as i understand it angeltest8 should now in metrics show zero "Effective Family Members" and zero "Alleged Family Members" and all other 22 relays should list his fingerprint as "Alleged Family Member".
