Atalui, item level no more than level 60

1. Atalui, which is located in the hideout, has an item level of all things that does not exceed level 60. And Atalui, which is located in The Ziggurat Refuge (Past), has item level above level 60.

2. Atalui, which is located in the hideout, has a different assortment from Atalui, which is located in The Ziggurat Refuge (Past).

3. Alva, which is located in the hideout, does not have a “buy sell” menu.

Yup, Having the same issue here. I've tried dismissing the vendors and even swapping hideouts to no success.

I have the same issue. Were you able to complete the quest Legacy of the Vaal? Maybe it is connected.
