Hello Hneel,
Is this inside a Library folder by chance? If so, this would be normal. While all
Included Folders and subfolders in a library will always share the same folder view. You can have separate "Arrange by" view settings in each right click -> New -> Folder created in the library itself though.
Only in normal folders in Windows Explorer will they be applied per folder.
Hope this helps for now,
Shawn
