Coding issue

When a user creates a site and they log in to change there store setting it will not save any setting in relation to the pay pal settings for the store.

To reproduce the error do the following steps:

1. Create a brand new site.

2. After site is created click Manage Your Market.

3. Log in with user name and password used to create site.

4. Click on Store Settings.

5. Click on Payments.

6. Type an email in the PayPal Email Address textbox.

7. Click Save Settings Button.

8. The PayPal Email Address textbox will be empty, when it shouldn't

Does anyone have input on where I need to change this in the code and how to change it?
