Issue generating just one word

[Casey Picker]

I'm trying to generate just one word for a meta field, but sometimes 2 or 3 words get generated. Here are the settings I'm using: http://p.tri.be/Kgc9Pr/2CdGaQ9o

Also, if I use 100 for the weight field, no values are ever added. Changing to 99 seems to fix it.
