I've tried with my location account set to Brazil and didn't worked, so I've changed to Canada and it worked
For some reason I can't understand they ignored all months before September.
I was in crunch time by September and early October, so makes sense I've played less than average
My realistic list of most played games this year is:
1) Animal Crossing ~650 hours
2) Splatoon 2 ~270 hours
3) Fire Emblem Three Houses ~240 hours
4) Dragon Quest XI ~85 hours
5) Hollow Knight ~75 hours
