Wreath of Snakes (Extreme) No longer appears on my Duty Finder

World name: Phoenix
Character name: Fox Tails
Class/Level: Level 70 White Mage

Hello, I have cleared the Wreath of Snakes and talked to The Wandering Minstrel for Extreme, which it said I have unlocked. For a few days it had appeared on my Duty Finder normally and i've been grinding to get the iLvl up to enter. Now that I have reached it, I went to go queue for it but it's no longer there.

I have been to the Ruby Sea, back to The Wandering Minstrel and nothing comes up about it, despite it already accepted and part of my Duty Finder originally. I'm not sure if this is a bug or not but it's really odd that I had it and now it's disappeared with no way of me getting it back on my Duty Finder.

Did you check under the High-End Duty tab?

...Thank you, I didn't even think about doing that. That's what months of leaving the game does to you.
