Raid finder - Black Ring Citadel not in rotation

Last week (week starting 18 January 2021) the raid finder instance was “The Palace of Cetriss: The Emerald Wizard”.
Therefore this week (week starting 25 January 2021), I believe should be “Black Ring Citadel”. However the raid finder instance is “Thoth-Amon’s Stronghold: Lower Floor”
Thank you for looking into this issue.
