Amazon.com gets rewritten to https://nimbus_als.ampxdirect.com/amazon?sub1=speeddial&sub2 and so on

I have Amazon.com as the URL for a dial, but when I click the dial, it gets rewritten to nimbus_als.ampxdirect.com

and the page does not load. If I type in the Amazon URL in the address bar the website opens. I deleted the dial and recreated it and still the same result. Thinking it was a cache or cookie issue I cleared all but still am getting the same website error. My other dials are not getting rewritten, why is Amazon?
