Expeditions Logbooks area level should go above area level 81

I am in deep endgame on SFF and I was excited to see logbook drop in area 82, only to discover that even though the item level of Logbook is 82, the area level it provides is still 81. It would help expedition to be more relevant in deep endgame I think.
I don't know if there could be some ballance issues if we had this, but it feels very unintitive that max level area is 81.

BTW, logbook its a map? Yes. So its must be to use tablet on this map.
