Confused about Savage rules..?

[Viuiji]

Hi,

So I got a group together for A1S in PF, including 2 FC member who have never ever cleared A1S.

When I went to enter I had no option for A1S, just A2S (I have cleared A1S this week). I accidentally hit it and we were all taken into A2S. We left and then no matter who was party leader, we could not enter back to A1S at all. I am assuming the game classed us all as 'cleared' A1S, which makes sense as we entered A2S.

My confusion however is that the party had 4 people (including my 2 FC mates) who had never cleared A1S before, ever. How is it possible that the game allowed then into A2S at all? Should there not be a message, similar to if you queue for Expert Roulette but someone has not yet unlocked one of the dungeons, you get a message that '1 or more party members has not met the requirement'

As a result, we had to disband and there was one quite upset party member (understandably), as they can now get no loot or manifesto this week.

Can someone help me understand why this happened, and if this is how it works, should it work like this?
