Notes not sorting properly?

I use the notes section on dramas to organise my Plan to Watch list, track when it's starting, whether or not it has subtitles, completed dramas I just haven't gotten to watching, etc. There are probably better ways to do this but it works  for me. The only issue I'm noticing is that when I try to sort the notes they don't always go in alphabetical order? Which is how I would assume it to work. 

(Also apparently I can't attach an image?) Notes screencap

I use notes so that i know the order in which i finished them! when i try to sort it doesn't work. numbers or letters, it wont sort
