Dawntrail Sightseeing Log Paintings

When I finished Endwalker sightseeing Log, the paintings were available on the
Joyous Painter. I have finished the sightseeing Log for Dawntrail, i have the achievement Happy Trails but the
Joyous Painter does not have any of the paintings for this Log.

Am I missing a step that is needed to open this up? Is there a different NPC in Dawntrail that has them? What am I missing? OR are the paintings are just missing from the game?
Will they ever be available to buy?

Being able to purchase them after finishing the log is my main reason for doing this Log.

iv just finished mine too and yeah im looking for the paintings too it seems very anticlimactic

The paintings have not been added yet. We're expecting to see them in 7.1.
