Subscription settings trusted devices

Under my subscription settings in the two factor tab, norton says that I have a larger number of trusted device than I have installs for. I am unable to set the devices that are trusted but there is the option to remove the trust.  How can I see what devices are set to be trusted by norton.  This renewed subscription cost a butt load of money and I should be able to see every aspect of what,where norton is being used so that I can validate my product.
