After much research and much reading… I found the answer via another post on this website. I had to increase my php settings to allow more variables to be inputed.
max_input_vars = 3000
suhosin.post.max_vars = 3000
suhosin.request.max_vars = 3000

Eliot, I know this issue is not related to your plugin, but just a php setting. However since it seems like a few people have already experienced the same issue, maybe you could have common solutions as this one placed somewhere easy to find in your support forum.
