In the security section, there are IP addresses that are listed as authorized networks. One of mine is not one of my IP addresses. It is from another state. If I try to remove it, it says:
"Some fields are invalid; please fix them."
Sometimes Internet Providers use locations that seem far away. You could look up the address and see who it belongs to.
Regardless, the only ones that could help would be the CS Team; you can contact them via the 'Support' link above/below and 'Submit a Ticket' for assistance.
