When I look into my total Stats it appears that I only started in February 2016 even though I already joined in 2007!

When I drill down to my host list then the data seem to be o.k.

Even the timelines are almost plausible. How come, that the combined data ignore everything before February 2016 even though the host data reflect the timelines more or less correct???
