I used to be able to see all the triumphs required to unlock the seal. But after finishing the main 53 step quest line last week, two triumphs suddenly became secret. I believe they were the ones for collecting the caches and the mysteries as I don't see those on there anymore. Was hoping it would be fixed by this weeks update. Kinda annoying to have to wait 3 weeks until the specific shattered realm I need returns again so I can finish those specific triumphs, assuming it gets fixed before then.
