Duty finder problems

[JonBigwood]

I can't join the hard level roulette or the trials roulette.

Now I am guessing you need to complete some established dungeons for the roulette to work, I have one ??? in hard mode (I didn't complete Pharos Sirius) and 4 ??? on the trials roulette. That may be the reason.
Up to now I could do High level roulette without having unlocked Pharos S.

There is a list of dungeons or trials you have to complete if you scroll down. ??? are the ones not completed (but you don't know which are.)
It seems Ultima is not needed, I have completed it and it is not on the list. Or there's a bug. And it does not depend on the class you are joining with, I have checked with my alt who hasn't completed all the dungeons and they appear on the list.

Edit: Now I see your list, Hydra and Chimera are not on my list although I did the relic quest and won there (but before they were on DF.) So my 4 missing would be Hydra, Chimera, Battle on the Big Bridge and The Whorleater (Hard)

If you look at the requirements, the low level says you only need to fulfill the requirements for 2 or more duties, unlike the hard and trials who have a list of dungeons you have to have completed.
