Different graph data then in table

I have noticed that on my profile, last week data for South Africa trips was 28, now is 31, but when i check graph last few days are like i didn't flight at all.
I asked friend to go to my profile, to check, and again in table i had 31 trips and graph is showing 31.

PS
Maybe that is intentional cause data is updated every week, but if that is true, why i need monthly view if 1/4 of graph is flat line?

There is a confirmed report on the graphs not updating here I believe.
