Sample Bar Charts missing third item (color same as background?)

[billross]

I just downloaded phppresentation and when I build the sample_05_bar.php on many of the charts the third item in the first series (2009 Mar) can't be seen in the pptx because it is the same color as the background. When I try making my own charts I get the same problem. I have attached my sample pptx
I am using :
