Different systems have different rules on the casing of the name of the system. Those with a capital letter appear before those starting with lower case (this includes second letters ect. The alphabet order is A-Z then a-z
i.e. a system called eSystem will appear at the bottom of the Category list when really this should be in the same position in a dropdown list as ESystem.
This has always been the place but would be a nice simple UI improvement
