To-Do List Additions

How bad is this?: Works but buggy

When I try to add my own assignments manually to the to-do list they say they're uploaded but then it doesn't show up at all on the list. Also, I have been having trouble with just a few assignments not being able to be marked complete. So when I check off the checkbox it doesn't go away.
