So, recently I had just hired a new staff member for my company, and, they were at 0 effectiveness for "Inactivity" right from the moment I hired them, despite being active. I had kept them around for a couple of days just to make sure that the problem wouldn't just correct itself, which it didn't. To note, none of my other employees which I have hired at the same time as them have had this issue, it was just this one person.
