I am using the latest version.
Well there is a beta version 17.1.2286 and there is the regular release 17.1.2286 (confusing). If you took part in the beta testing you need to check you have the latest (build 17.1.3394).
I ran a Smart Scan but nothing was found, so no Details button for me.
Clicked the Notifications bell, which has a Details button (presumably this is what you are talking about). I can click that details button till the cows come home and no details (presumably because nothing was found) and no restart of the Smart Scan.
