Windows Dwarf Scroll donated, not working

[Laranja]

I already donated the four scrolls to the library and I can't communicate with the dwarves, then I tried to talk to gunther again as a user recommended and it didn't work, I try to talk to him And he only thanks me for the help in the library, but does not offer me any translation books.

Can you share some screenshots? What does your museum look like? What is the menu like when you speak to Gunther? What happens when you speak to the dwarf?
