Leads Discrepancy

So yesterday on my home page I apparentely generated 23 leads. However, when i click my reports, the green graph shows that I generated 31 leads. And the text below my graphs compliments the home page results. So my question is - what is up with the graph telling me I generated 8 more leads than my homepage? Has anoybody experienced this? How did you deal with it? Should I contact CJ telling them of this discrepancy? Or is everything that is happening normal? By the way, this has happened on many dates. Losing from about 1-9 lead(s).
