Chronological order of tasks

When I enter in times for tasks it doesn't order them correctly (chronologically) automatically, and when I manually reorder them they snap back to where they were after a couple seconds. It also doesn't let me change the length of time a task will take to more than an hour, it snaps back to the original 1 hr time after a couple seconds as well. 

Other than that, loving the app!
