I've noticed this is a recurring thing, and happened in Shadowbringers too, but for most jobs & classes it is less of an issue, since you either have a gathering log to refer to or the quest actually shows where to go.

The exception to this I've realised is fisher. I've been working intermittently on the Studium quest for fisher, and every time I've logged on & decided to continue I open my journal, just to see this:

Description: T'laqa Tia has high hopes that your partnership will bear fruit.
Objectives: Catch garjana wrasse and deliver them to T'laqa Tia
There's no information about what kind of fish it is, what kind of bait it requires, where the fish can be found or anything. I don't even know how much collectability it requires.

What even is the point of a quest journal if I have to return to the NPC who gave me the quest, every time I need a reminder of what to do??

The only reason I have not been as bothered by it before, is that the quests that are guilty of the same, I worked on right away instead of picking up and doing later.
