Check on the Raid Info what was the difficulty of the raid you did. I did a test and it seems it’s working only on 10-man difficulty, as their blue post mentioned..
I did Mogu’shan Vaults on Normal 25-man, and Terrace on Heroic 10-man.
Vaults got a weekly reset for me, but Terrace was daily.
However, Sha of Anger registered for me as a weekly lockout.
