Visual Interactions not working properly

Hello everyone,

I have a table which divides my data into three geographic regions, and a pie chart that categorizes it according to industry sector.  I want to be able to click on a region in the table and highlight the pie chart accordingly.

However, it is only highlighting the pie chart for two of the the three regions; when I select the third region, the pie chart is replaced by one that contains ONLY the data for that particular region.  

For example: when I click on US, the pie chart highlights correctly:

However, when I click on Europe, the entire pie chart changes to represent ONLY Europe (ie, the pie chart is no longer the sum of Asia, Europe and the US):

Any ideas why this might be happening?  This is a very simple model consisting of only one file (ie, no relationships between multiple files at all). 

Thanks for all replies!
