How do I turn off Fluther notifications?

I tried going to “My Account”, and then I click on notifications and disable all notifications by unchecking the boxes. I click save and leave the page. When I come back to my account and check my notification settings, they’re all set back to checked boxes again and I can’t get them to stay unchecked so that I don’t receive notification emails. How can I fix this?? Anyone else having this problem?
