CFCHARTDATA item occasionally not displayed

Question

CF7 & CF8 I have a bunch of these cfchartseries to
display a horizontal stacked bar chart in Flash. Depending on the
order of how the data is presented invariably one of the item names
is not displayed on the far left of the chart. Once it was the
second item name. I switched it around and then the third item name
was not displayed. If I changed the name to something else it might
display.
Essentially I should see 4 bars. To the left of the each bar
and to the left of y axis I should see
Open Due | XXXXXXXXXXXXXXXXXXXXXX
Past Due | XXXXXXX
Phase Complete | XXX
Not Yet Due | XXXXXXXXXXXXXXXXXXXXXXXX
However, "Phase Complete" is showing up blank in Flash but in
JPG it is showing up. Here's a little clip
<cfchartseries type="horizontalbar" seriesLabel="October
2008" seriescolor="red">
<cfchartdata item="Open Due" value="18">
<cfchartdata item="Past Due" value="0">
<cfchartdata item="Phase Complete" value="0">
<cfchartdata item="Not Yet Due" value="0">
</cfchartseries>
<cfchartseries type="horizontalbar" seriesLabel="November
2008" seriescolor="yellow">
<cfchartdata item="Open Due" value="0">
<cfchartdata item="Past Due" value="0">
<cfchartdata item="Phase Complete" value="50">
<cfchartdata item="Not Yet Due" value="0">
</cfchartseries>

One other thing:
in SM53 I can see an error in the log:
Log message: ProductInconsistenDBException
Log name: com.sap.spc.document.rfc.ChangeItemHandler
Any ideas?
