Tasks in the current sprint that we mark as 'Done' are moved to the next sprint as well which is not expected as per our requirements here.
I am under the impression when the 'Done' Status is at the far right (last column) under board settings, then they should be removed automatically from the sprint when we complete. But here, they are going to the next sprint.
Also the 'Done' field is set to 'Done' under category value.
I am using NextGen project.
