Dont Starve Hamlet resolution problem

[Nucleer]

Hello KLEI I bought the DLCs of your game Dont Starve and I am very happy with it, but there was an error in the downloadable content Hamlet. Although the game is full resolution, 1920*1080, it shows a lower resolution, I tried many things but it did not work. I deleted the game with all the cloud files and reinstalled it, but it did not change and this happened when I installed Hamlet on my computer. The resolution decreased in all downloadable content, including Hamlet, but it shows 1920*1080 in the settings. Please help
