Paypal Express & Directory Plugin - Losing settings. Defaults to Sandbox

Any idea why this is happening? I am trying to put my directory payment settings to "Live" from "Sandbox" but it keeps kicking back to "sandbox". The site I am working on is girlygirldirectory.com.

I also have a ? about the payment box. As you can see, it is showing 2 options. The first is correct ($12.00 annually), but why is there a second box that just says USD? Rather, I would like this to be a "free" option for Tutuology.com members. Can I set that up easily?

Lastly, I cannot figure out where/how to modify the "sign up" button. It is returning a 404/checkout page.
