Spaces are important!
In your example, the first command has an extra space at the beginning of the command.
That command returns with an error
The second command has no space there, and works.
Did you think that both would work?
Maybe with that file only some of the other options with tag -S work. So looks like it doesn't like Aqua as an argument for -S.
Aqua, LoginWindow, Background, StandardIO, System.... how about StandardIO or System?
