[2023] I did not receive the final delivery for the Swordfish Sword at the fishing hut

Hello AC players,
After spending hours of fishing in my game time, I delivered all the fish at Arth’s fishing hut, but I don’t get a final delivery to get the Swordfish sword.
Arth tells me to come back later! Why??
Here is my gameplay video:

Please help?
Thanks in advance.
