I assume you are using Niara theme 🙂
If yes, than good luck, as you will need to manually edit the theme, since nobody tested how it works together with AUEC module ,once decision was made that Niara becomes official TB theme.
As Niara hides all default checkboxes/radio buttons and replaces them with colored ones.
So problem appears in every module that shows own checkbox/radio button based on default theme preferences, as Niara theme hides this by default and therefore nothing is visible.
In my opinion, hiding default checkboxes has not ben thought well.
Or you can replace following file in:
/modules/advancedeucompliance/views/templates/hook
hookOverrideTOSDisplay.tpl
