Seeking history meta quest disapearing randomly after accepting them

Since these quests have a lot of lore in them and find its continuation in several forms at the archive with brynthe and dagran, this is unacceptable that these quest are bugged. As mentioned above they disappear after accepting this weekly quest or they don’t even pop up. Meanwhile some people have the quest and some do not. For me i have progress by only having 2 chapters unlocked at the archive while there are 4 currently. I accepted the third after many weeks of no follow up on this quest and when i finally did: poof gone. Also the quest is not shareable. It is the one where u collect titan discs. I have reported this multiple times to no avail. More people mentioned this on wowhead. So please blizzard fix this. Anyone else?
