3.0 Reboot Calendar not working

Hello, I have installed the WhatPulse a few days ago so I still have the premium status. I use Windows 10.

On the “Computer Uptime” window in the “Uptime” tab it shows that I had 5 reboots today. Then when I go to the “Reboot Calendar” window I see today case/square in a red color (blue in attachment) and with “No reboots found”.

Is that normal?
